Chemicals work practice

Training. These events underscore the importance for chemical worker training to include hazard information and lessons learned from accidents, previous studies, and similar events involving the same chemicals and chemical work practices... 

Included ia the OSHA regulations are standards for safe work practices such as lock-out/tag-out and confined space entry, personal protective equipment, storage of hazardous materials, welding process, forklift operation, and requirements for fire protection. Basically, all activities within a chemical facihty are covered by OSHA standards. 

As discussed in Chapter 2, The Toller Selection Process, evaluating the site s safe work practice procedures should have been a part of the review during the toller selection process. Still, new materials may indicate a need to revise or develop special procedures to address unique chemical and physical hazards. New hazards such as vacuum, ciyogenics, ultra-high pressure, or new rotating equipment could be introduced. Medical monitoring requirements or special handling and spill response procedures for the toll s raw materials and products may indicate a need to write or revise safe work practices. 

Process Overview The process overview includes topics related to the equipment configuration, chemical and physical changes achieved in the specific toll, and special safe work practices related to the operations, maintenance and materials. Emphasis should be given to any new equipment and chemical hazards the startup team will encounter. 

All employees, working with highly hazardous chemicals must understand the safety and health hazards (29CFR1910.1200 - the Hazard Communication Standard) by knowing the properties of the chemicals with which they work, safe operating procedures, work practices, and emergency action. 

Walk-through survey An examination or inspection of a workplace involving a review of hazardous materials present and/or used, observation of work practices, and consversations with individuals to identify all of the actual or potential chemical, physical, biological, and ergonomic hazards. 

The physical and chemical characteristics of the liazardous substance must be listed. Tliese include items such as boiling and freezing points, density, vapor pressure, specific gravity, solubility, volatility, and product s general appearmice and odor. These characteristics provide important iiiformation for designing safe and healtliful work practices. 

Preventive measures include everything from safe work practices to training programs, good housekeeping, regular audits, administrative and engineering controls, and chemical-protection equipment. 

To ensure that an operation is under control may necessitate atmospheric monitoring this is summarized in Chapter 9. General safety considerations, administration and systems of work requirements, including elementary first aid, are summarized in Chapter 11. For example, the recommended strategy is to include provision for appropriate first aid procedures within the system of work before specific chemicals are brought into use to so order work practices that the risk of exposure is minimized and in the event of an accident involving any but the most trivial injuries — with no foreseeable likelihood of complications or deterioration — to seek immediate medical assistance. 

A second reason is due to the absence of preliminary risk analyses in everyday activities involving chemical substances. Only sensitive activities are subjected to analyses (mainly because of what is at stake and for financial reasons). This is due to, on the one hand, the absence of literature on how to diagnose a priori risks and, on the other hand, the difficulty of such an analysis,(the chemistry being difficult). Finally, preliminary risk analyses are not part of managerial experience and work practice. 

Nowell, Edward. Certain chemical works with the true practice gathered into a true method by Edward Nowell. B. M. Sloane 2567. R.A.M.S., 1982. 40p. 

The submitters used practical grade anthranilic acid from Mallinckrodt Chemical Works. 

OSHA recommends that worker exposure to this chemical is to be controlled by use of engineering control, proper work practices, and proper selection of personal protective equipment. Specific details of these requirements can be found in CFR 1910.1003-1910.1016.
