Chemical Hygiene Coordination Committee
The committee includes the CHO and representatives from business area (appointed by line management). These representatives are referred to as site chemical hygiene contacts.
• Provides opportunity for communication between plant sites.
• Facilitates continuous improvement of safety policies and practices.
• Meets at least annually to review CHP and training.
• Completes CHP training.
• Implements the CHP including but not limited to practices and procedures for the following:
ο particularly hazardous materials,
ο prior-approval process,
ο laboratory inspections.
• Supervises CHP training by all laboratory personnel.
• Supports and enforces laboratory standards program.
• Provides ongoing ownership.
• Ensures that local safety procedures are written, training is provided, and procedures are followed.
• Designates a local chemical hygiene contact (CHC) (by site, building, division, or department).
Site/Area Chemical Hygiene Contact
• Completes CHP training.
• Serves as contact person for CHO and laboratory personnel for site/area CHP implementation.
• Represents site/area on CHCC.
3. If the timing of the task cannot be changed and you still feel it must be accomplished during a period when the laboratory is empty, is there any other person trained in laboratory procedures who can accompany you while you work?
4. If not, is there anyone else within the building who could act as a “buddy” to check on you periodically during the time that you feel you must work alone?
5. If no one can accompany you and you cannot find a “buddy,” do not proceed with the work. The situation is unsafe. Speak to your supervisor or the organizational safety office to make arrangements to complete the work in a safe manner.
2.C.3 How to Avoid Routine Exposure to Hazardous Chemicals
Many chemicals and solutions routinely used in laboratories present a significant health risk when handled improperly. The Swiss physician and alchemist Theophrastus Phillippus Aureolus Bombastus von Hohenheim (1493–1541), who took the name Paracelsus later in life in homage to Celsus, a Roman physician, is known as “the father of toxicology.” Paracelsus is famous for his quote, “What is it that is not poison? All things are poison and nothing is without poison. It is the dose alone that makes a thing not a poison” (Dillon, 1994). Today, in that same spirit, trained laboratory personnel are encouraged to reduce personal risk by minimizing exposure to hazardous chemicals and by eliminating unsafe work practices in the laboratory.
The OSHA Laboratory Standard defines a hazardous chemical as one “for which there is statistically significant evidence based on at least one study conducted in accordance with established scientific principles that acute or chronic health effects may occur in exposed persons.” Note that this definition is not limited to toxic chemicals and includes corrosives, explosives, and other hazard classes. Routes of exposure to hazardous materials include contact with skin and eyes, inhala-
