Safety & Health

Toxicity

BIO-SOFT N-900 is slightly toxic orally (LD₅₀ > 2,000 mg/kg), and at 10% active causes slight skin and moderate eye irritation.

Workplace Exposure

Occupational exposure can occur primarily through skin contact or via inhalation of vapors and mists. Engineering controls, personal protective equipment, and other workplace practices should be used to control these exposures.

Storage & Handling

Storage & Handling Information

Bulk Storage Recommendations: BIO-SOFT N-900 should be stored in vessels of 316 stainless steel or fiberglass with a corrosion liner. Heating and agitation are recommended for outside storage. Material should be stored between 95 - 131°F (35 - 55°C). An internal hairpin coil of 316 stainless steel with low pressure steam (under 50 psig) should be used if heating is required. Pumps, pipes and transfer lines should be 316 stainless steel.
