The OSHA laboratory standard applies to all employers engaged in the laboratory use of hazardous chemicals (as defined below) to control ooccupational exposure to hazardous chemicals in laboratories. The final standard became effective on May 1, 1990.
The OSHA standard requires that the employer must develop and carry out the provisions of a written Chemical Hygiene Plan. The purpose a CHP is to provide the necessary work practices, procedures, and policies to ensure that employees are protected from exposure to potentially hazardous chemicals in use in their work area. Employees must be trained in the plan.
1. Understand and comply with the OSHA Lab Standard (below)
2. Provide the necessary work practices, procedures, and policies to ensure the protection of employees from potentially hazardous chemicals in use in their work area.
2. Copies of both the OSHA lab standard and its appendices and the must be available to all potentially affected employees.
3. Includes general guidelines for working in the laboratory, such as
a. Document and train employees to become acquainted with the location of fire extinguishers, eye wash stations, and drench showers
b. Have injury response plans documenting how to respond to an injury to employee, completing an accident report, information about Workman's comp., use of company physicians and regular testing and medical monitoring.
c. General rules for working in the laboratory.
1. Become acquainted with the location of fire extinguishers, eye wash stations, and drench showers
2. Publish and train on emergency response procedures
3. Fire alarms may not alert fire department. They must be called
4. Maintain Material Safety Data Sheets for all dangerous chemicals and products and keep them readily available to employees.
5. Bottle labels often provide information on appropriate personal protective equipment (i.e. eye, hand, and body protection as well as fume hood use requirement.
