Just before the Hurricane, the above headline was in
Newsday, on
August 19, 2011, regarding a
chemical accident where two
cleaning chemicals were accidently mixed causing 54 workers to become ill and requiring some of them to be hospitalized. Workers were treated for symptoms including convulsions, dizziness, nausea,
shortness of breath and vomiting. Unfortunately, the report does not discuss the specific chemicals that were mixed. It does mention that the company was using a new chemical for cleaning and did not fully purge the old cleaning chemical out of the system.
This incident highlights the importance of providing
training to staff when a new chemical is added to the facility. This will ensure the hazards of the new chemical will be understood and any problems that may occur with mixing chemicals are fully understood. The most important part of this training is the
Material Safety Data Sheet (MSDS). The MSDS is created by the manufacturer to warn the users of its chemicals about the dangers of the chemical, the
personal protective equipment (PPE) needed, first aid necessary if exposed, the path of exposure, and other important information. The training on the new chemical should be on the specifics of handling the chemical including any PPE needing to be used when using the chemical, the first aid procedures should an exposure occur, proper storing of the chemical, and any other chemicals that should be avoided or prevented from coming into contact with the new chemical. Maybe if this training was done the individuals responsible for purging the system would have been more cautious.
The current issue of the Industrial Hygiene News has an excellent article on laboratory safety called "A Chemical Lab Safety Refresher" written by Mr. Phillip G. Retallick, who is the Senior Vice President Regulatory Affairs for Clean Harbors. The article covers the typical information regarding lab safety - training, storage, disposal, labeling, and compliance audits. One of the more interesting sections was the discussion on the requirements of a good industrial hygiene program. This section discussed the need for a worksite analysis and a well-defined and monitored work practices. The need for a Chemical Abstract Service (CAS) Registry software and routine monitoring of the air to ensure lab staff are protected is not typically discussed. The assumption is that sufficient ventilation will handle any potential problems. However, how do you know you have sufficient ventilation? Monitoring is the best way to ensure that. The article list important resources such as the Environmental Protection Agency's (EPA) "Environmental Management Guide for Small Laboratories" and the Occupational Safety and Health Administration's (OSHA) hazardous materials portion (Section H) of 29 CFR 1910. A short and to the point article on Lab Safety.
