5. Applies to all “employers engaged in the laboratory use of hazardous chemicals and where relatively small quantities of chemicals are used on a non-production basis.”
Definitions:
Laboratory use (scale): small quantities of multiple chemicals that can be handled and manipulated by one person and do not simulate a production process in any way (e.g. commercial quantities of chemicals). Scope and Application of
6. Hazardous Chemicals
7. Cont’d. Health hazard - any chemical that may produce acute or chronic health effects in exposed employees
Examples of these chemicals include:
Carcinogens
Toxic Agents
Reproductive Toxins
Irritants
Corrosives
Sensitizers
Hepatotoxins
Neurotoxins
Agents that damage the lungs, skin, eyes, or mucous membrane
8. Employees can be exposed to hazardous chemicals by 3 main ways: Chemical Exposures
9. Health Effects Exposure to hazardous chemicals produces Acute and/or Chronic health effects.
Acute health effects develop over a very short period of time (e.g. hours or days).
Classic examples: HCN (Anoxia); NO2 (Pulmonary Edema)
Chronic health effects develop over a very long period of time (e.g. years).
Classic example: Asbestos (Asbestosis/Mesothelioma)
10. How am I supposed to know all this stuff about chemicals??? Material Safety Data Sheet (MSDS)
11. Material Safety Data Sheet (MSDS) MSDSs are your KEY to understanding the hazards of a particular chemical!!
Product Name
Name, Address, Telephone (Manufacturer)
Date of Preparation
Name of Hazardous Chemical(s)
Physical/Chemical Characteristics
Routes of Entry
Exposure Limits
Carcinogenic Status, if any
Handling Precautions
Health Hazards
MSDSs must be maintained and kept up-to-date.
There must be a MSDS for every single chemical in the laboratory!!!
MSDSs must be immediately available and all employees should know their location.
12. Container Labeling At a minimum, all chemical containers must have an appropriate label which contains:
Identity of hazardous chemical(s)
Appropriate hazard warnings -- this can include words, pictures, or symbols. The hazard warnings must adequately describe the physical and health hazards associated with that particular chemical.
In most cases, chemical containers that come to UL-RTP will have permanent labels affixed to them. Never remove a label from a chemical container.
If you transfer chemicals from one container to another, the new, temporary container must also be labeled as described above.
13. Labeling Cont’d.
14. How can chemicals be detected in my work environment? Qualitative and Quantitative measurements are the two basic methods used to determine if chemicals are being released into the work environment.
15. Qualitative Monitoring Methods For chemicals with good warning properties (e.g. low odor threshold), employees can detect the presence of vapors and fumes in the ambient environment with their sense of smell. Sources of chemical odors can arise from chemical spills or from faulty equipment, such as a malfunctioning chemical fume hood.
The easiest, most obvious qualitative method is using your eyesight to detect chemical releases. Small smoke plumes and liquids spilled on the floor/lab surface are some examples.
16. Quantitative monitoring is the most accurate way to determine the airborne concentrations of chemicals.
The Safety Officer (Phone #) can conduct these measurements if there is reason to believe laboratory employees are being overexposed to hazardous chemicals.
If the results of the air monitoring show that employees are or may be overexposed to a particular hazardous substance, engineering controls must be implemented, if feasible, to reduce employee exposure to below OSHA PEL’s.
17. What type of instruments are used to monitor the workplace?
18. Monitoring Instruments Cont’d... Continuous monitoring devices also measure concentrations of airborne contaminants quantitatively.
As the name indicates, these devices monitor the work environment continuously and provide a direct-reading capability so employees can obtain instantaneous measurements in their work environment.

22. Appropriate PPE At a minimum, all laboratory employees must wear safety glasses and chemical protective gloves while in the laboratory.
23. PPE Cont’d.

25. Evacuations
26. Emergency Medical Care
27. Chemical Spills
28. COMPANY NAME Chemical Hygiene Plan What is a CHP?
Written document outlining SOPs and general safe work practices and handling of chemicals in the laboratory setting. It is required by law (OSHA’s Lab Standard).
What about COMPANY NAME’S CHP?
Defines responsibilities; contains SOPs (general), provisions for site-specific SOPs, guidelines for chemical fume hood use, employee exposure assessments, medical consultations/exams, employee training, container labeling, MSDS management, and others.
Where can you find COMPANY NAME’S CHP?
DESCRIBE LOCATION OF THE WRITEN PLAN.
An electronic copy of our CHP can be found online at PROVIDE ADDRESS, IF APPLICABLE.
