WAC 296-828-20005   Chemical hygiene plan.  

     You must:

     • Develop and carry out a written chemical hygiene plan (CHP) that will protect your employees from hazardous substances in the laboratory and keep exposure levels below those listed in chapter 296-841 WAC, Airborne contaminants.

     • Make sure the written plan is readily available to employees and their representatives.

     • Include the following elements in your written CHP:

     – The names or job titles of the chemical hygiene officer, other personnel responsible for implementing the CHP, or when appropriate, the members of a chemical hygiene committee.

     – Standard operating procedures that provide employee protection when working with hazardous substances.

     – Criteria for how you will select and use control measures to reduce employee exposures to hazardous chemicals, especially chemicals known to be extremely hazardous.

     – Additional employee protection for select carcinogens, reproductive toxins, and chemicals with high degree of acute toxicity. The following will be considered, when appropriate:

     ▪ The establishment of exposure control areas.

     ▪ Containment devices, such as fume hoods or glove boxes.

     ▪ The safe removal of contaminated waste.

     ▪ Procedures for decontamination.

     – Specific measures to make sure fume hoods and other protective equipment provide proper and adequate performance and are properly functioning.

     – The circumstances when specific laboratory operation, activity, or procedure requires prior approval from the employer or their designated representative before implementation.

     – A description of how you are going to train and inform your employees about laboratory use of hazardous chemicals.

     – A description of your provisions for medical consultations and medical examinations.

     • Review and evaluate the effectiveness of your written CHP at least annually and update as necessary.
