Potential chronic health

Prolonged inhalation may be harmful. Components Species Test Results: Hydrochloric acid (CAS# 7647-01-0) Rat - Inhalation LC50: 3124 ppm, (1 hour) Rabbit - Dermal LD50: 5010 mg/kg

ECOLOGICAL INFORMATION

Ecotoxicity: Because of the low pH of this product, it would be expected to produce significant ecotoxicity upon exposure to aquatic organisms and aquatic systems. Aquatic Toxicity: This material is toxic to fish and aquatic organisms. Most aquatic species do not tolerate pH lower than 5.5 for any extended period. Fish Toxicity: Fish LC50 Mosquito fish: 282 mg/l, 96 hours Fish LC50 Bluegill: 3.6 mg/l, 48 hours Persistence and Degradability: Not biodegradable. Hydrochloric acid will likely be neutralized to chloride by alkalinity present in natural environment. Bioaccumulative Potential: No data available. Mobility in Soil: Hydrochloric acid will be neutralized by naturally occurring alkalinity. The acid will permeate soil, dissolving some soil material and will then neutralize.

Other hazards

No other adverse environmental effects (e.g., ozone depletion, photochemical ozone creation. DISPOSAL CONSIDERATIONS Collect and reclaim or dispose in sealed containers at a properly licensed waste disposal site. This material, if not neutralized, must be disposed of as hazardous waste. Do not allow this material to drain into sewers/water supplies. Do not contaminate ponds, waterways or ditches with chemical or used container.
