Engineering control of hazards

American Institute of Chemical Engineers Control of Hazardous Material Spills, Washington DC, 1974... 

Most or the incidents described were the result or not rollowing good engineering practice. Some violated the law, and many more would if they occurred today. In the United States, they would violate OSHA 1910.147 (1990) on The Control of Hazardous Energy (Lock Out/Tag Out) and the Process Safety Management (PSM) Law (OSHA 1910.119, in force since 1992). which applies to listed chemicals above a threshold quantity. The PSM Law requires companies to follow good engineering practice, codes, industry consensus standards, and even the company s owm standards. OSHA could view failure to follow any of these as violations. 

Functions such as industrial hygiene (the protection of worker health against occupational hazards) and hazardous waste mcmagement involve the control of hazards arising from processes. As with process safety, you can attempt to use engineering-based solutions alone, but will find that ongoing control of hazards is difficult to achieve. Designing-in hazard control and... 

Section 4.2 consolidates the requirements for control of hazardous operations (see def.) including written operating procedures, safety equipment and engineering controls, safe work practices, and fire prevention and fire protection. 

Personal protective equipment (PPE) is last in the hierarchy of hazard control. PPE is less desirable than engineering and administrative controls for the control of hazards but is still critical. The appropriate PPE fitted correctly is a reliable barrier against known hazards. The biggest drawback against PPE is that some workers are careless about their selection of PPE for a job and choose ineffective PPE or they do not ensure that it is properly fitted and used. The function of PPE is to protect the user s entire body, including the respiratory system, eyes, hearing, head, hands, etc. 

Safety engineering is the application of engineering principles to the recognition and control of hazards [p. 12],... 

Safety practice is the identification, evaluation, and control of hazards to prevent or mitigate harm or damage to people, property, or the environment. That practice is based on knowledge and skill as respects Applied Engineering, Applied Sciences, Applied Management, and Legal/Regulatory and Professional Affairs. 

Safety Basis means the combination of information relating to the control of hazards at a nuclear facility (including design, engineering analyses, and administrative controls) upon which DOE depends for its conclusion that activities at the facility can be conducted safely. 

One of the principal methods used for the engineering control of occupational health hazards. The process causes fresh air to circulate to replace contaminated air that is simultaneously removed. There are several different kinds of ventilation. See also Local Exhaust Ventilation Natural Ventilation. 

Although not exhaustive, OSHA s guidelines and recommendations include policies, procedures, and corrective methods to help prevent and mitigate the effects of workplace violence. Engineering controls remove hazards from the workplace or create a barrier between the worker and specific hazards. 

The prevention and control of hazards can be accomplished in many ways. The primary way is through the reporting of hazards by employees and the correction of hazards by supervisors or other company qualified personnel. Second, employers can use preventive maintenance programs, special emphasis programs, training, workplace audits, engineering controls, administrative controls, and, as a last resort, personal protective equipment.

Analysis Step 1 Host is a creating employer because it caused employees of S to be exposed to the air contaminant above the PEL. Step 2 Host failed to implement measures to prevent the accumulation of the air contaminant. It could have met its OSHA obhgation by implementing the simple engineering control of covering the drums. Having failed to implement a feasible engineering control to meet the PEL, Host is citable for the hazard.
