or, normally unoccupied remote facilities.
Clean Air Act Amendments of 1990 enacted? - ANSWERSlaw that OSHA enact the PSM Standard
The areas that the CAA specified for coverage included: - ANSWERS• Written safety information
- workplace chemical and process hazards, equipment, & technology
• Hazard assessment - potential for catastrophic consequences (range of release, exposure
group, etc.
• Consultation with employees on development of the hazard analysis and associated plans.
This also included access to the developed plans
• Employers had to do something about the findings from the hazard assessment - they couldn't
just put it on a shelf to collect dust
,• Employers had to periodically review (audit & update) the original assessment
• Employers had to develop and implement written operating procedures
• Employers had to make the written operational and safety information available to employees
and train them
• Employers were required to ensure that contractors and contract employees are given the
information and trained on it. NOTE: It is of interest that this is the only place in OSHA that this
requirement is actually written.
• Emergency response training for both the employees and contractors
• QA Programs
• Maintenance Programs
• Pre-startup Safety reviews
• Change Management
• Incident investigation

Define "catastrophic release" according to the PSM Standard? - ANSWERSA major uncontrolled
emission, fire, or explosion, involving one or more highly hazardous chemicals that presents
serious danger to employees in the workplace.
How would you determine if the chemicals used in processes at your facility were governed by
the OSHA PSM Standard? - ANSWERSAppendix A if the chemical is listed match the quantities in
hand, when so than the chemical would be governed.
