NIOSH Resources

NIOSH Pocket Guide to Chemical Hazards
DHHS (NIOSH) Publication No. 2005-149
Exposure limits, Respirator Recommendations, First Aid, more...
The Pocket Guide is a source of general industrial hygiene information on several hundred chemicals/classes found in the work environment. Key data provided for each chemical/substance includes name (including synonyms/trade names), structure/formula, CAS/RTECS Numbers, DOT ID, conversion factors, exposure limits, IDLH, chemical and physical properties, measurement methods, personal protection, respirator recommendations, symptoms, and first aid.

International Chemical Safety Cards
An ICSC summarizes essential health and safety information on chemicals for their use at the "shop floor" level by workers and employers in factories, agriculture, construction and other work places.

Documentation for Immediately Dangerous to Life or Health Concentrations (IDLH)
The IDLH documents the criteria and information sources that have been used by NIOSH to determine immediately dangerous to life or health concentrations.

NIOSH Manual of Analytical Methods (NMAM)
NMAM is a collection of methods for sampling and analysis of contaminants in workplace air, and in the blood and urine of workers who are occupationally exposed.

Fatality Assessment and Control Evaluation (FACE) Program
The FACE program concentrates on investigations of fatal occupational injuries.  The primary intent of this program is to provide interested users with access to the full text of hundreds of fatality investigation reports.

NIOSH ALERT: Preventing Deaths of Farm Workers in Manure Pits
DHHS (NIOSH) Publication No. 90-103 (May 1990)
This Alert describes seven deaths from asphyxiation (suffocation) that occurred during two incidents involving entry into manure pits.

NIOSH Criteria Documents: Criteria for a Recommended Standard: Occupational Exposure to Hydrogen sulfide
DHHS (NIOSH) Publication No. 77-158 (May 1977)
Contains a standard for mitigation of exposure to Hydrogen sulfide to prevent adverse effects over a working lifetime.
