Abstract
An industrial hygiene survey of the Howes Leather Company, Inc., (SIC-3111) Curwensville, Pennsylvania was conducted to determine worker exposure during vegetable tanning operations. The company processed steer hides producing sole, belt, and welting leather using vegetable tanning processes. Approximately 1,220 cattle hides were processed per day. A total of 120 persons were employed in production and administrative positions. Detailed personnel records were maintained for each employee and were kept indefinitely. The company had no formal industrial hygiene program but did administer a formal safety program including routine meetings and monthly safety tours. Potential worker exposures included calcium-oxide (1305788) and hydrogen-sulfide (7783064) (unhairing operation), ammonia (7664417) (bating operation), sulfuric-acid (7664939), (salt pickling and vegetable tanning operations), tannins and sodium- bisulfite (7631905) (vegetable tanning operations), mineral-oil (oil wheeling and sponging operations) and oxalic-acid (144627) (bleaching operation). Area and personal samples were collected in the facility during the day shift and analyzed for ammonia, nitrosamines, hydrogen-sulfide, sulfuric-acid, oxalic-acid, mineral- oil, and particulates. Only ammonia exceeded OSHA standards. Recommendations for reducing worker exposure to ammonia included increasing ventilation in the beam house in the areas of the dehairing and defleshing machines and cropping tables and providing respirators in the areas of the highest ammonia levels.
