A lab specific Standard Operating Procedure (SOP) is required when a laboratory engages in an activity or procedure not covered by the chemical hygiene plan.
A SOP may also be required when laboratory work involves the use of certain types of hazardous chemicals or physical hazards or when more specific language is required to safely perform a procedure. Examples may include working with a pyrophoric or reactive chemical, changing a pyrophoric gas cylinder, work with a particularly hazardous material, etc.
A lab specific SOP is required:
Once a SOP is written it must be reviewed and approved by Environment, Health & Safety. After approval, all lab workers using that SOP must be trained on its content and the training must be documented. A copy of the training record must be attached to the SOP when placed in the lab copy of the chemical hygiene plan.
