Risk identification 12 (organic peroxides), 7 (flammable materials), 1 (hazardous goods) applies to metal catalysts, bleaching agents, deodorants, coupling agents for unsaturated polyesters, initiators for aggregation, and accelerators for the curing of sulfur rubber

Scope of application: used as a metal catalyst, bleaching agent and deodorant, coupling agent for unsaturated polyester, initiator for aggregation, and vulcanization accelerator for rubber.

Environmental Impact of Tert-butyl Peroxide

Health damage

Route of entry: inhalation, ingestion, absorption through the skin.

Health damage: inhalation, ingestion, or absorption through the skin can harm the human body. It has a stimulating effect on the eyes, skin, mucous membranes, and respiratory tract. Inhalation can cause inflammation, edema, spasm, and chemical pneumonia, and pulmonary edema. Contact can cause burning sensation, cough, asthma, chest tightness, headache, nausea, vomiting, and other symptoms. It can cause allergic reactions.

Toxicological Materials and Environmental Behavior

Acute toxicity: LD50 410Mg/kg (rat, oral); 790Mg/kg (rat, dermal); LC50 1840Mg/m3, 4 hours (rat inhalation)

Hazard characteristics: flammable, with strong oxidizing properties. There is a risk of fire and explosion when exposed to high temperatures, sunlight, impact, or contact with oxidizers and flammable materials such as sulfur and phosphorus.

Combustible (dissolved) substances: carbon monoxide, carbon dioxide.

Emergency Response to Tert-butyl Peroxide

Emergency Response to Leaks

Quickly evacuate workers exposed to leakage to a buffer area and take protective measures, strictly limiting entry and exit. It is recommended that emergency response personnel wear self-contained positive pressure breathing masks and wear fire protective clothing. Do not come into direct contact with the leaked material. Try to disconnect the source of leakage to avoid entering confined spaces such as sewers and drainage channels. For small leaks: mix and absorb with inert, wet, cold, and non-flammable materials. Store in plastic containers. You can also use a moisturizing emulsion made from non-flammable thickeners for cleaning, dilute the detergent after washing and put it into the sewage system. For large leaks: construct embankments or dig to assist; cover with foam plastic to reduce vapor disasters. Transfer to tank trucks or specialized collectors using explosion-proof pumps, collect and purchase, or transport to waste disposal sites for disposal.

Preventive Measures

Respiratory safety protection: wear a filter-type toxic gas mask (half-face mask) when there is a possibility of contacting its vapor.

Eye safety protection: wear chemical safety goggles.

Body safety protection: wear high-pressure polyethylene protective suits.

Hand safety protection: wear rubber gloves.

Other: smoking is strictly prohibited on the job site. Maintain a stable lifestyle.

Emergency Measures

Skin contact: remove contaminated clothing, and thoroughly wash the skin with soap and cold water.

Eye contact: lift the upper eyelid and rinse with running cold water or saline. Seek medical attention.

Inhalation: quickly move to a fresh air area. Maintain the smoothness of the respiratory system. If breathing is not smooth, provide oxygen. If inhalation stops, immediately perform external chest compression. Seek medical attention.

Ingestion: drink a certain amount of warm water, vomit. Seek medical attention.

Fire extinguishing methods: firefighters must operate in explosion-proof shelters. Foam extinguishing agents: water, foam plastic, carbon dioxide, and crushed soil. Avoid approaching fires casually. In case of fire around raw materials, maintain the cooling of containers with tap water.
