Hazardous Substance Safety

2 THE JOINT COMMISSION HAZARDOUS MATERIAL WASTE CATEGORIES 

Corrosiveness Any substance with the ability to degrade the structure or integrity of another substance, object, or material. Examples include acids and alkalis. Ignitability Any material that can too readily burn or ignite, including some chemicals that can auto-ignite upon contact with the air. 

Reactivity Any substance with the ability to readily combine with other chemicals to produce a sudden or violent release or heat/energy. 

Toxicity Any material with the capability of causing illness or death in man, animals, fish, or plants, or capable of damaging the environment.

When handling strong exothermic processes or hazardous substances, safety issues also became a major driver for the use of microreactors. Finally, several academic studies can be found in the literature focusing on the analysis of mass transport and flow characteristics within microfluidic charmels by using electrophilic aromatic substitutions as model reactions.

In the past ten years laboratory workers have become increasingly conscious of safety in the laboratory environment. We have therefore in three places in Chapter 1 (pp. 3 and 33, and bibliography p. 52) stressed more strongly the importance of safety in the laboratory. Also, where possible, in Chapters 3 and 4 we draw attention to the dangers involved with the manipulation of some hazardous substances.

Hazardous Substances Data Bank (HSDB) on compact disc from the Canadian Center for Occupational Health and Safety (can buy at CCOHS web site). "The HSDB(R) (Hazardous Substances Data Bank(R)) database contains data profiles on 4,500 potentially toxic chemical substances. It is created and updated by specialists at the U.S. National Library of Medicine. Compiled from an extensive range of authoritative sources, HSDB is widely recognized as a reliable and practical source of health and safety information. Much of the data is peer reviewed. 

Record potential pollutant sources in the building. Note the locations of major sources. Major sources such as large items of equipment can be recorded on the floor plan. Record the names and locations of chemicals or hazardous substances used or stored within the building, such as those that may be contained in cleaning materials, biocides, paints, caulks, and adhesives. Ask your suppliers to provide you with Material Safety Data Sheets. You may be unaware of the potential hazards... 

Safety issues include threats to the safety of workers or nearby communities during the implementation or operation of the corrective measures (i.e., fire, explosion and exposure to hazardous substances). 

MSDS Material Safety Data Sheet - a document that provides pertinent information and a profile of a particular hazardous substance or mixture. An MSDS is normally developed by the manufacturer or formulator of the hazardous substance or mixture. The MSDS is required to be made available to employees and operators whenever there is the likelihood of the hazardous substance or mixture being introduced into the workplace. Some manufacturers prepare MSDS for products that are not considered to be hazardous to show that the product or substance is not hazardous. 

Flazardous waste sites are divided into as many or as few zones as necessary to protect worker health and safety. Work zones are established to prevent the spread of hazardous substances from contaminated to clean areas. Radiological work zones should be considered compatible with hazardous waste work zones, differing only in terminology. Diagrams, sketches, and maps should be used as often as necessary and constantly updated and communicated so that workers can be sure that they are appropriately protected [3]. 

Medical monitoring and surveillance programs enable occupational health professionals to identify adverse health effects caused by exposure to hazardous substances and conditions and to discuss plans with site workers, industrial hygienists, safety professionals, and line management to prevent exposures and protect workers. These goals can be accomplished through two objectives ... 

If the PPE is personal in nature and can be used by the employee off the job, the payment issue may be left up to labor and management. Examples cited in the memorandum include safety shoes, nonspecialty safety glasses, and cold-weather gear. OSHA makes it clear that, If shoes and cold-weather gear is subject to contamination of hazardous substances and cannot be safely worn off-site it should be paid for by the employer. ... 

In 29 CER 1910.120 (a)(3) it is stated that responses to incidental releases of hazardous substances where the substance can be absorbed, neutralized, or otherwise controlled at the time of release by employees in the immediate release area, or by maintenance personnel, are not considered to be emergency responses in the scope of the standard (HAZWOPER). The term incidental is the key term. Workers need to be trained as to what type of situations would be considered incidental. In general, if the employees actions to clean or control the release do not and likely would not put them in jeopardy (from a safety and health viewpoint), the act would be considered incidental. 

In addition, responses to releases of hazardous substances where there is no potential health or safety hazard (i.e., fire, explosion, or chemical exposure) are not considered to be emergency responses. Keep in mind that qualified personnel who are trained to clean up incidental...

A nonprofit organization that is the authoritative source for developing standards for minimizing the possibility and effects of fire and explosion conducts fire safety programs provides information on fire protection, prevention, and suppression develops systems for prevention and suppression offire and explosions arising from hazardous substances. 

It might be assumed that if an examination of the plant layout is being carried out, the future plans, as they affect the site layout, will be known. This is not always the case therefore, management should be questioned at the beginning of the project. Particular attention should be paid to hazardous substances that may be used on the site, and the health and safety document should be consulted.
