The Supreme Court has reinforced the theory of the First Amendment as a "safety valve," reasoning that citizens who are free to to express displeasure against government through peaceful protest will be deterred from undertaking violent means. The boundary between what is peaceful and what is violent is not always clear. For example, in this 1965 photo, Alabama State College students participated in a non-violent protest for voter rights when deputies confronted them anyway, breaking up the gathering.

Under the safety valve rationale, citizens are free to make statements concerning controversial societal issues to express their displeasure against government and its policies. In assuming this right, citizens will be deterred from undertaking violent means to draw attention to their causes.

The First Amendment, in safeguarding freedom of speech, religion, peaceable assembly, and a right to petition government, embodies the safety valve theory.

These and other decisions rest on the idea that it is better to allow members of the public to judge ideas for themselves and act accordingly than to have the government act as a censure. The Court has even shown support in cases concerning obscenity or speech that incites violent action. The safety valve theory suggests that such a policy is more likely to lead to civil peace than to civil disruption.

Justice Louis D. Brandeis recognized the potential for the First Amendment to serve as a safety valve in his concurring opinion in Whitney v. California (1927) when he wrote: “fear breeds repression; . . . repression breeds hate; . . . hate menaces stable government; . . . the path of safety lies in the opportunity to discuss freely supposed grievances and proposed remedies; and the fitting remedy for evil counsels is good ones.”

A “safety valve” is an exception to mandatory minimum sentencing laws. A safety valve allows a judge to sentence a person below the mandatory minimum term if certain conditions are met.  Safety valves can be broad or narrow, applying to many or few crimes (e.g., drug crimes only) or types of offenders (e.g., nonviolent offenders). They do not repeal or eliminate mandatory minimum sentences. However, safety valves save taxpayers money because they allow courts to give shorter, more appropriate prison sentences to offenders who pose less of a public safety threat. This saves our scarce taxpayer dollars and prison beds for those who are most deserving of the mandatory minimum term and present the biggest danger to society.

The Problem:Under current federal law, there is only one safety valve, and it applies only to first-time, nonviolent drug offenders whose cases did not involve guns. FAMM was instrumental in the passage of this safety valve, in 1994. Since then, more than 95,000 nonviolent drug offenders have received fairer sentences because of it, saving taxpayers billions. But it is a very narrow exception: in FY 2015, only 13 percent of all drug offenders qualified for the exception.

Mere presence of even a lawfully purchased and registered gun in a person’s home or car is enough to disqualify a nonviolent drug offender from the safety valve,

Even very minor prior infractions (e.g., careless driving) that resulted in no prison time can disqualify an otherwise worthy low-level drug offender from the safety valve, and

The Solution:Create a broader safety valve that applies to all mandatory minimum sentences, and expand the existing drug safety valve to cover more low-level offenders.

The primary purpose of a safety valve is to protect life, property and the environment. Safety valves are designed to open and release excess pressure from vessels or equipment and then close again.

The function of safety valves differs depending on the load or main type of the valve. The main types of safety valves are spring-loaded, weight-loaded and controlled safety valves.

Regardless of the type or load, safety valves are set to a specific set pressure at which the medium is discharged in a controlled manner, thus preventing overpressure of the equipment. In dependence of several parameters such as the contained medium, the set pressure is individual for each safety application.

The safety of labourers are compromised despite of precautions and safety measures adopted by the various industries. Therefore, a full proof planning and strategies are extremely necessary for ensuring safety of the workers. In oil drilling industries, workers are exposed to high risk as it involves some of the life threatening procedures and a number of things could go wrong. The biggest disaster that the offshore industry encountered was the Deepwater Horizon Blowout on April 2010 (North et al., 2014). The accident involved 11 workers who were declared dead as a result from that event. In my opinion, this disastrous event lead many people to believe that the safety measures followed in the offshore industry is not up to the mark and may lead to fatal incidents. In this case, the reason behind the blowout was the negligence of the BP plc. that lead to the blowout killing 11 people and creating a long term oil spill disaster (Matejek & Gössling, 2014). However, I believe that the safety measures and trainings provided in this field of industry is high and a number of training sessions are provided to the labourers in order to avoid any harm. For instance, the BOISET training offers all the workers of this industry with the general offshore training and emergency training in escaping the disasters that the workers might encounter. Along with this, the workers are provided with Helicopter and Underwater escape training that is extremely essential and toughest part of the training. The rigorous part of the training ensures that the workers of this industry are able to escape the scene of vicious event efficiently. The response team in case of any disaster are quick to act and provide first aid to the labourers. Another industry that have hazardous effect on its labourers are the Marine industry. One of the significant disaster that the Marine industry encountered was the Piper Alpha explosion on July 1988 that resulted 167 death of crewmembers on board (Swuste, Gulijk & Zwaard, 2017). The investigation run by then senior member of Scottish judiciary Lord Cullen exposed the cause of the tragedy and provided recommendations that were later included in the safety management, training and regulations (Bennear, 2015). The investigation even made a huge contribution in bringing changes such as mandatory use of automatic safety valves on rigs in order to ensure to cease the flow of hazardous fluids that might cause explosion. I believe this inclusion in the system benefited the marine as well as the oil drilling industry immensely as it significantly decreased the risk of explosion caused by toxic and hazardous fluid leakage. The first case study also highlights the stereotypical discrimination that exists in such professions. For instance, the number of female professionals in such industries are extensively low compared to male professionals. The reasons range from a generalised thinking of the society that female would not be competent enough to deal in such harsh situations. This conception has lead to gender inequality in almost every profession including in these industries as well. In my opinion this issue could be eradicated if the majority of society challenges the shallow thought that have been existent for a long period of time.

The third case study provides the possible hazards that are more likely to occur in offshore industries or in other industries such as construction or mining industry. The severity of these hazards are maximum, as I believe that the range of accidents mentioned in this case study may lead to life threatening incidents and thus, causing a negative impact on worker’s health. This might lead to employers abandoning their position in these industries and shift towards those professions that ensures full safety to a workers health. However, I believe that proper training and suitable amendments in the required area could ensure wellbeing of a labourer. In my opinion, bringing a change in the safety measures and the necessary changes in equipment’s as well would ensure a better functioning that would ultimately secure the workers’ health. Now, discussing about the fourth and final case study, it highlights the significance of product safety. The most basic criteria that a company has to fulfil is to ensure its consumers that the products manufactured are safe. Bringing out a quality product in the market is a necessary obligation along with building a trustworthy relationship with the consumers. Therefore, in order to provide tests and certification of the products for ensuring a quality of the products, the TUV SUD corporation delivers thousands and thousands of organisations with certifications, trainings and tests which ultimately makes sure the safety check of the products manufactured by various organisations and companies (www.tuev-sued.de, 2018). The significance of the product checks is of highest priority as it may refrain a possible accident from occurring. In my view, when a company manufactures a product, everyone involved with the company are responsible for its impact on consumers. The negative impact could cause fatal accidents, which involves the consumers. For instance, in this case study, it is mentioned that the over charged battery of a drone caused a devastating fire in 2016 that involved the death of an individual and was a valued consumer (Huiwen, 2018). Such incidents could bring in grave reputation towards the companies and eventually deteriorate the profit of it. The job of providing quality products to the consumers and building trust between the organisation and the consumers benefit both the company as well as the consumers in the market.

The course that I opted for Safety Health and Environment Management course would benefit me in my career since the profession that I look forward fall under the category of hazardous industry (Sousa, Almeida & Dias, 2014). The various safety measures related to various industries which was thoroughly discussed throughout my course helped me gain knowledge and made my decision to choose a specific profession in the future (Glendon, Clarke & McKenna, 2016). The course could provide me with the basic knowledge of safety measures and potential hazards that I might have to face in my career in future. It also benefited me with the history of certain regulations that were amended in recent times. This course has extensively offered instances that how lethal the hazards may occur in various circumstances. It has even made my choices clear to choose as the various case studies in described in the course help me critically evaluate the circumstances that may arise in a specific industry. For instance, the above-discussed case study gave me the various training protocols that are involved in an oil drilling industry.

The knowledge that the course offered me helped me gain confidence in managing any organisation or industry’s safety and health related activities (Sayre, 2014). I acquired the knowledge of varied laws that are linked with safety and health regulations of a business organisation. The course even helped me gain knowledge towards the recent amendments that are based on the safety and health activities that concerns the wellbeing of a labourer. With the help of the knowledge, I would be able to apply certain approaches that shall help me deal with the changed policies and regulations regarding the health and safety of products as well as the labourers associated with an organisation.

In my opinion the ability and passion to work in a certain field will always boost an individual to work in that field no matter how hard of hazardous circumstances arises. However, with a proper knowledge and adequate training one could always avoid any fatal accidents in his or her profession and efficiently complete his or her task. In addition to this keeping, an optimistic outlook would definitely help me to achieve success in whichever field I opt for in future (Carver & Scheier, 2014). In addition to this, I would always try to appeal the customers or consumers with the product or service that I am assigned to deliver. Customer or consumer’s satisfaction should be kept as highest priority (Pan & Nguyen, 2015). In any profession, it is significant to satisfy the customers or consumers with quality products and services. Therefore, keeping this in mind I would deliver the task that I would be assigned with in future. The recent course has changed my mind to join the technical service corporation such as TUV SUD that ensures the safety of the products manufactured by a company or an organisation. This industry may not involve the hazardous working circumstances in its field of work, however, it ensures that other companies follows the safety guidelines and qualifies the safety of a product. This enables the safety of the consumers who would be using the product.

The learnings that I acquired during this course work were useful for me in various ways. The various case studies that I have to go through during the course helped me analyse the key faults that lead to huge disasters in various field of work. It even help me detect a basic ideology that how a minute negligence could lead to a hazardous situation and even cause fatal outcomes. Prior to the course, I had a belief that providing quality work from an individual’s end is mandatory. However, after the completion of the course it made me realise that it is instead mandatory to put a joint effort in providing a quality product or service for the consumers (Costa, Passos & Bakker, 2014). Some of the case studies suggests the fault of an entire team lead to the fatal disasters and jeopardised the safety of the labourers. In addition to this, the course helped me realise that in any field of profession an individual requires proper and suitable training. In case of hazardous profession such as oil drilling industry or marine, training plays one of the key roles in an employee’s career as it would support him or her in dealing with difficult circumstances that might arise in the job (Dupre, Meixner & Kielty, 2014). However, the course additionally enlightened the fact that training alone would not help a labourer to escape hazardous situation in distinctive professions. Along with training the routinely check-up of the equipment’s is necessary for avoiding any hazardous situations (Strand & Lundteigen, 2016). Therefore, the safety management system must be updated from time to time in order to adapt with the changing technologies. This will decrease the rate of fatal circumstances from happening at the workplace.

Even though the course that I opted offered me extensive knowledge about the safety management activities and its significance in various industries. However, if I had to restart my course once again, I would have maintained a file where I would have compiled the different industry’s measures to control hazardous situation. This would have helped me keep a self-track of the varied range of situations and the effective measures to cope with those situations. This practice would have helped me in my future professional career, as I would have an access to the compiled files during my course work. In addition to this, I would have taken various case studies outside the course for instance from newspapers and other online sources. This would have helped me to gain critical thinking or rather enhance my analytical skills in hazardous situations. The articles available online would have provided me with practical measures that were adopted in practical scenarios. A compilation of these measures would have come in immense importance in securing good grades in my course.

The Safety Health and Environment Management course proved to be extremely beneficial for me. I was extremely fond of the various case studies that I had to analyse. In doing so, I attained knowledge about varied range of safety health policies of various countries (. The course even offered an in-depth process of necessary steps that should be taken in a specific situation. It was interesting to know the specific escape measures that workers of oil drilling industry had to take in case of any disaster happened at the site of work. The course even helped me to select a specific career option related to safety management.

This course extensively provided an insight towards the probable health hazards that a worker might had to face in certain industry. A detailed strategy and measures to deal with these hazards was included in this course as well (Hoyos & Zimolong, 2014). However, I look forward to learn and acquire further knowledge related to safety health and environment management activities. The various online training courses are a great way to enhance my skills in this particular field of profession. Additionally, the videos available online would give me a virtual knowledge about the hazards that might occur in various industries. I would opt to study the Masters course that would further help me acquire knowledge and develop my environment management skills. I would be able to further develop my skills reading news articles related to prior disasters that occurred in distinguished industries. The professional career that I chose is Health and Safety Consultant. In order to land the specific job I have to sharpen my analytical skills that would help me detect the possible hazards that a certain industry might face in future. I would also need to focus on my communication skills since the profession that I have chosen is of a Health and Safety consultant. Therefore, I would need to give out a thorough strategy to my clients and even have to explain them the strategies with logical reasoning. Hence, I would require working on my communication skills as well. In addition to this, I would have to choose from various training session that would further accelerate my skills as Health and Safety Consultant.

because in this design they are running below recommended operating temperatures and voltages which means they are going to last longer, even though valves are incredibly robust when it comes to longevity compared to capacitors for instance. This means there is as much chance of the valve dieing as other components, so swapping it out doesn’t seem to justify a socket.

it simplifies the build process, because there are no sockets the valve wont stick out as much meaning it can go on the same pcb as potentiometers etc. This means less circuit boards and less faff

over time especially in a touring synth valve sockets on the front of modules get looser and looser. This causes a bit of a temperamental module where valves sometimes wriggle themselves to a loose connection.

also another thing I thought worth mentioning is handling valves with your fingers. In the application of the safety valve it doesnt really matter, even in most household applications of valves it doesn’t really matter handling these with your hands. purely because they aren’t on all the time and most importantly they don’t get hot enough. handling with your fingers is more an issue in valves in places like radio studios and power stations of old where operating temperatures were a lot closer to the crunch point in glass and over such a long amount of time that yes oils and such could pose a corroding issue.

In the safety valve because the 12ax7 is a pretty darn robust valve and the fact that the safety valve operates below recommended temperature of the 12ax7 its fine its the same as holding a glass with mulled wine in it

A safety valve must always be sized and able to vent any source of steam so that the pressure within the protected apparatus cannot exceed the maximum allowable accumulated pressure (MAAP). This not only means that the valve has to be positioned correctly, but that it is also correctly set. The safety valve must then also be sized correctly, enabling it to pass the required amount of steam at the required pressure under all possible fault conditions.

Once the type of safety valve has been established, along with its set pressure and its position in the system, it is necessary to calculate the required discharge capacity of the valve. Once this is known, the required orifice area and nominal size can be determined using the manufacturer’s specifications.

In order to establish the maximum capacity required, the potential flow through all the relevant branches, upstream of the valve, need to be considered.

In applications where there is more than one possible flow path, the sizing of the safety valve becomes more complicated, as there may be a number of alternative methods of determining its size. Where more than one potential flow path exists, the following alternatives should be considered:

This choice is determined by the risk of two or more devices failing simultaneously. If there is the slightest chance that this may occur, the valve must be sized to allow the combined flows of the failed devices to be discharged. However, where the risk is negligible, cost advantages may dictate that the valve should only be sized on the highest fault flow. The choice of method ultimately lies with the company responsible for insuring the plant.

For example, consider the pressure vessel and automatic pump-trap (APT) system as shown in Figure 9.4.1. The unlikely situation is that both the APT and pressure reducing valve (PRV ‘A’) could fail simultaneously. The discharge capacity of safety valve ‘A’ would either be the fault load of the largest PRV, or alternatively, the combined fault load of both the APT and PRV ‘A’.

This document recommends that where multiple flow paths exist, any relevant safety valve should, at all times, be sized on the possibility that relevant upstream pressure control valves may fail simultaneously.

The supply pressure of this system (Figure 9.4.2) is limited by an upstream safety valve with a set pressure of 11.6 bar g. The fault flow through the PRV can be determined using the steam mass flow equation (Equation 3.21.2):

Once the fault load has been determined, it is usually sufficient to size the safety valve using the manufacturer’s capacity charts. A typical example of a capacity chart is shown in Figure 9.4.3. By knowing the required set pressure and discharge capacity, it is possible to select a suitable nominal size. In this example, the set pressure is 4 bar g and the fault flow is 953 kg/h. A DN32/50 safety valve is required with a capacity of 1 284 kg/h.

Coefficients of discharge are specific to any particular safety valve range and will be approved by the manufacturer. If the valve is independently approved, it is given a ‘certified coefficient of discharge’.

This figure is often derated by further multiplying it by a safety factor 0.9, to give a derated coefficient of discharge. Derated coefficient of discharge is termed Kdr= Kd x 0.9

Critical and sub-critical flow - the flow of gas or vapour through an orifice, such as the flow area of a safety valve, increases as the downstream pressure is decreased. This holds true until the critical pressure is reached, and critical flow is achieved. At this point, any further decrease in the downstream pressure will not result in any further increase in flow.

A relationship (called the critical pressure ratio) exists between the critical pressure and the actual relieving pressure, and, for gases flowing through safety valves, is shown by Equation 9.4.2.

Overpressure - Before sizing, the design overpressure of the valve must be established. It is not permitted to calculate the capacity of the valve at a lower overpressure than that at which the coefficient of discharge was established. It is however, permitted to use a higher overpressure (see Table 9.2.1, Module 9.2, for typical overpressure values). For DIN type full lift (Vollhub) valves, the design lift must be achieved at 5% overpressure, but for sizing purposes, an overpressure value of 10% may be used.

For liquid applications, the overpressure is 10% according to AD-Merkblatt A2, DIN 3320, TRD 421 and ASME, but for non-certified ASME valves, it is quite common for a figure of 25% to be used.

Two-phase flow - When sizing safety valves for boiling liquids (e.g. hot water) consideration must be given to vaporisation (flashing) during discharge. It is assumed that the medium is in liquid state when the safety valve is closed and that, when the safety valve opens, part of the liquid vaporises due to the drop in pressure through the safety valve. The resulting flow is referred to as two-phase flow.

The required flow area has to be calculated for the liquid and vapour components of the discharged fluid. The sum of these two areas is then used to select the appropriate orifice size from the chosen valve range. (see Example 9.4.3)
