Answer:

A. Examples of laboratory hazards:

In general, there are three types of hazards personnel may encounter while working in laboratories at the NIH.  

Possible hazards include:

• Biological Hazards – bloodborne pathogens

• Chemical Hazards – carcinogenic, flammable, or corrosive materials

• Physical Hazards – pyrophoric materials, lasers or radiation.

It is possible, even common, for a single laboratory to have types of hazards associated with more than one of  

these categories at once. Engineering controls should be used as primary barriers, functioning to contain the  

hazards. Personal protective equipment (PPE) should be used in combination with engineering controls to  

reduce the risk of worker exposure to laboratory hazards. A risk assessment should be used to determine the  

hazards associated with a particular laboratory or laboratory operation, and establishing which engineering  

controls should be utilized and what PPE should be selected. Information on how to perform a risk assessment  

is described in Biosafety in Microbiological and Biomedical Laboratories 5th Edition. For assistance with  

performing a risk assessment and selecting proper PPE, please contact your Institute's Safety and Health  

Specialist, or the Division of Occupational Health and Safety.  

B. Appropriate laboratory attire, laboratory coats and applicable standards:

While in a laboratory at the NIH for any reason, all personnel must wear appropriate clothing attire that prevents  

direct contact of materials with the skin. Examples of attire that is appropriate includes long pants or leg  

coverings and closed toe shoes. In addition, a task appropriate laboratory coat, as determined by a risk  

assessment, must be worn while performing laboratory operations. Following a thorough risk assessment,  

guidance to the selection of laboratory coats can be obtained from Tables 1 and 2. Table 1 lists the three types  

of laboratory hazards and the applicable laboratory coat material standards. Table 2 provides a more detailed  

description on the application of these standards and examples of laboratory coats that meet these standards.  

Table 1. Summary of laboratory hazards and applicable test standards

Type of Laboratory Hazard Applicable Test standard

Biological Hazards ASTM F1670 (penetration by synthetic blood) and  

ASTM F1671 (bloodborne pathogen exposure)

Liquid or Chemical Hazards AATCC Method 42 (resistance to the penetration of  

water by impact) and ASTM F903 (liquid chemical  

barrier)

Physical Hazards NFPA 701 or 2112 (flame propagation tests)

The standards listed in Table 2 serve as standardized testing methods to determine protection levels of materials  

against certain hazardous or hazard surrogates. These standards should be considered when selecting a  

laboratory coat material when working with the hazards that correspond to the applicable hazard or hazard  

surrogate tested. These testing methods only test the material and do not test the complete laboratory coat  

making it important to consider characteristics of the laboratory coat such as seams, stitches and where the  

openings, snaps or buttons are located when selecting a laboratory coat. A complete description of the  

standards can be viewed by contacting your Institute's Safety and Health Specialist,
