Lab Process Safety Management

Process safety management was created under OSHA in July of 1990 due to major disasters from accidental chemical releases in the past which resulted in many deaths. A process is defined as any activity involving a highly hazardous chemical including using, storing, manufacturing, handling, or moving chemicals at the site. This contained requirements for the proper management of highly hazardous chemical hazards to ensure the safety of employees. This management system is complete, containing procedures, management practices while being integrated with technology. After many meetings they implemented 25 state plans which cover a variety from both private and public sectors. This standard mainly covers manufacturing industries that relate to chemicals, transportation equipment, natural gas liquids, and fabricated metal products. A company can also be under the process safety management if it contains more than 130 specific toxic and reactive chemicals that are listed as well as flammable liquids and gases in stock of more than 10,000 pounds.
There are fourteen elements of process safety management: process safety information, process hazard analysis, operating procedures, training, contractors, mechanical integrity, hot work, management of change, incident investigation, compliance audits, trade secrets, employee participation, pre-startup safety review, and emergency planning and response.
1.      Process safety information is a written form that companies must complete before they can conduct process hazard analysis. These forms will help both the employers and the employees to identify and understand the hazards associated with the chemicals they are using.  
2.      Process hazard analysis is an approach for identifying, evaluating, and controlling the hazards of processes involving highly hazardous chemicals. The first step is for the employer to do a hazard evaluation on every process done within the company that are covered by the standard. It must also address engineering and administrative controls with the hazards, facility siting, human factors, and hazards of the process.
3.      Operating procedures must be written down and easily available for all employees. These procedures must be consistent with the rest of the previous processes. The procedures must cover: initial startup, normal operations, temporary operations, emergency shutdown and normal shutdown.
4.      All employees must be properly trained. There is initial training, refresher training, which all must be documented.
5.      Contractors must go through the proper application processes. The employer must evaluate information on the contract employer’s safety performance for the past.
6.      The mechanics must be maintained in order to be at a certain performance level so it is safe for all employees.
7.      A hot work permit must be issued for work operations on or near a covered process.
8.      Management of change must be written and must contract employees whose jobs will be affected. Everything must be updated.
9.      All incidents must be documented and investigated properly.
10.   In case of an emergency there must be a set plan in place, employees must be trained.
11.   Employers must be evaluated to be in compliance with PSM every 3 years.
12.   Trade secrets must be kept within the company, but this information must become public to PSM.
13.   Employees, production, maintenance, and staff to be involved in all aspects of the PSM program at your site, and to have representation in the development, discussion, and eventual solution to issues around the process hazard analysis.
14.   Conduct pre-startup safety reviews of all newly installed or modified equipment;

Fire Safety in the Lab

Fire safety in the lab is extremely important. There are various aspects when it comes to safety, knowledge of chemicals, location of safety equipment and personal protective equipment as well as many others. In case of an emergency all employees should have the proper training to know where to go or if the emergency is containable, know how to use the fire extinguisher to put out the small fire before it spreads. Other safety equipment in the lab includes: pull alarms, safety showers, emergency use telephone, fire egress, and fire blankets. Employees that know all of these things are properly able to respond to a fire in the lab.
An example we looked at in class is from Duke’s Laboratory Safety Manual section 6, Fire Safety. In their instruction the employees are encouraged to follow the RACE method in case of a fire. The acronym RACE stands for: remove all individuals from the affected area, activate all the pull alarm and dial 911, close all doors and windows, and extinguish the fire. This facility follows the codes created by the National Fire Protection Association (NFPA) for guidelines in their own fire protocol.
Fire safety in the lab is extremely important. There are specific standards when it comes to storing flammable and combustible liquids or materials in the lab. Combustible liquids are defined as: any liquid with a flash point at or above 100 degrees F. Flashpoint is the temperature at which a particular organic compound gives off sufficient vapor to ignite in air. Flammable liquids are defined as a liquid having a flash point below 100 degrees F and having a vapor pressure greater than 2068.6 mm Hg at 100 degrees F. There are three classes of combustible and flammable liquids with Duke’s system. With the National Fire Protection Association has an extensive list of flammable and combustible liquids. Most labs narrow down these lists to make it more specific to the chemicals used in that lab. OSHA defines flammable liquids into four categories defined on their flash point and boiling point. OSHA also defines flammable solids as powdered, granular, or pasty chemicals which is dangerous if they can be easily ignited by brief contact with an ignition source. The NFPA has a diamond that is a symbol to identify the hazards that is used for fire fighters when entering the lab. Class IA and IB flammable liquids have a NFPA fire hazard rating of 4. Class IC flammable liquids are rated as a 3 and combustible liquids are rated as a 1 or 2. Four is the highest hazards for fire and the numbers one and zero are for lower hazards. This can be confusing for others because it is the opposite order for the GHS Hazard Categories. The fire hazard is on the upper middle part of the diamond.

Flammable chemicals should be stored in flammable storage cabinets. The volume of liquids that can be kept in storage cabinets is 20 gallons per one hundred square feet with a maximum of 10 gallons per one hundred square feet being Class I liquid. The requirements vary depending on the location and type of storage cabinet.

CFATS

Chemical Facility Anti-Terrorism Standards or CFATS is a program that regulates and identifies high risk chemical facilities to make sure that the proper security measures are in place. This program was approved by congress in 2007. The Department of Homeland Security has chemical security officers in all fifty states to enforce the regulations stated in the CFATS program. CFAT was put in place to discover the consequence of a successful attack on a facility (consequence), the likelihood that an attack on a facility will be successful (vulnerability), and the intent and capability of an adversary in respect to attacking a facility (threat).
In 2014, the President signed into law the Protecting and Securing Chemical Facilities from Terrorist Attacks Act of 2014 (“the CFATS Act of 2014”), which recodifies and reauthorizes the CFATS program for four years. This act revises the previous act and adds new regulations that did not previously exist. The most important change is the establishment of an Expedited Approval Program. This new program allows existing chemical facilities in Tiers 3 and 4 to move to an approved site security plan more quickly. Chemical facilities must pass a CFAT inspection to be compliant with the required standard. First, before the inspection takes place these chemical facilities that are given an Appendix A Chemical of Interest and ends up above the threshold limit then has 60 days to complete a Security Vulnerability Assessment and submit it to the Department of Homeland Security. A Security Vulnerability Assessment, which are vital in identifying chemical facility vulnerabilities in security. After this is submitted a chemical facility is given an initial Tier rating, 1 through 4. Then, after this is completed a chemical facility’s next step is to make and implement a Site Security Plan, which follow the CFATS requirements.
Appendix A, is a list of all the chemicals that are a security issue. It was first published in 2007 but it has been updated since then. These chemicals were chosen by the Department of Homeland Security looking at chemicals covered by the Environmental Protection Agency’s Risk Management Program, Chemicals included in the Chemical Weapons Convention, Hazardous materials, such as gases that are poisonous by inhalation; and Explosives regulated by the Department of Transportation. These chemicals are also split into three separate security issues: release, theft or diversion, and sabotage. Release is for chemicals that are flammable, toxic or explosive and when they are released from a chemical facility it has the potential to be life threatening or have severe adverse health effects. A theft or diversion classification of chemicals are those of which when stolen or diverted have potential to be used as weapons either directly or being converted into a weapon to create adverse health effects for humans. Sabotage is for chemicals that when mixed with other chemicals have the potential to create serious adverse health effects for humans.
