The early development of the
content relied on textbooks of occupational medicine (LaDou,
Rom, Rosenstock,
Sullivan & Krieger, and Zenz). The textbooks were
precursors of Haz-Map, which is like an electronic book. Another
important precursor was the NIOSH Sentinel Health Events
(Occupational). SHE(O)s first published by Rutstein et al. in 1983 and
updated by Mullan and Murthy in
1991. Sixty-four occupational diseases
were linked to causal agents and associated industries. See Haz-Map
Diseases by Category for the original SHE(O) diseases and the ones
now in Haz-Map.
