What to Know About Di-Tert-Butyl Peroxide
Fire Hazard
May explode from heat or contamination. May ignite combustibles (wood, paper, oil, clothing, etc.). May be ignited by heat, sparks or flames. May burn rapidly with flare-burning effect. Containers may explode when heated. Runoff may create fire or explosion hazard.
Health Hazard
Fire may produce irritating, corrosive and/or toxic gases. Ingestion or contact (skin, eyes) with substance may cause severe injury or burns. Runoff from fire control or dilution water may cause environmental contamination.
Reactivity Profile
The explosive instability of the lower dialkyl peroxides (e.g., dimethyl peroxide) and 1,1-bis-peroxides decreases rapidly with increasing chain length and degree of branching, the di-tert-alkyl derivatives being amongst the most stable class of peroxides. Though many 1,1-bis-peroxides have been reported, few have been purified because of the higher explosion hazards compared with the monofunctional peroxides. It is unlikely that this derivative would be particularly unstable compared to other peroxides in its class.
Potentially Incompatible Absorbents
Use caution: Liquids with this reactive group classification have been known to react with the absorbents listed below. More info about absorbents, including situations to watch out for：
- Cellulose-Based Absorbents
- Expanded Polymeric Absorbents
Flammability and Explosibility
Di-Tert-Butyl Peroxide is a flammable liquid and a highly reactive oxidizing agent. Pure TBHP is shock sensitive and may explode on heating. Carbon dioxide or dry chemical extinguishers should be used for fires involving Di-Tert-Butyl Peroxide.
Reactivity and Incompatibility
Di-Tert-Butyl Peroxide and concentrated aqueous solutions of TBHP react violently with traces of acid and the salts of certain metals, including, in particular, manganese, iron, and cobalt. Mixing anhydrous Di-Tert-Butyl Peroxide with organic and readily oxidized substances can cause ignition and explosion. TBHP can initiate polymerization of certain olefins.
Storage and Handling
Di-Tert-Butyl Peroxide should be handled in the laboratory using the "basic prudent practices" described in Chapter 5.C supplemented by the additional precautions for work with reactive and explosive substances (Chapter 5.G). In particular, Di-Tert-Butyl Peroxide should be stored in the dark at room temperature (do not refrigerate) separately from oxidizable compounds, flammable substances, and acids. Reactions involving this substance should be carried out behind a safety shield.
Accidents
In the event of skin contact, immediately wash with soap and water and remove contaminated clothing. In case of eye contact, promptly wash with copious amounts of water for 15 min (lifting upper and lower lids occasionally) and obtain medical attention. If Di-Tert-Butyl Peroxide is inhaled or ingested, obtain medical attention immediately. In the event of a spill, remove all ignition sources, soak up the Di-Tert-Butyl Peroxide with a spill pillow or noncombustible absorbent material, place in an appropriate container, and dispose of properly. Respiratory protection may be necessary in the event of a large spill or release in a confined area. Cleanup of anhydrous Di-Tert-Butyl Peroxide and concentrated solutions requires special precautions and should be carried out by trained personnel working from behind a body shield.
Disposal
Excess Di-Tert-Butyl Peroxide and waste material containing this substance should be placed in an appropriate container, clearly labeled, and handled according to your institution's waste disposal guidelines.
Response Recommendations
Isolation and Evacuation
IMMEDIATE PRECAUTIONARY MEASURE: Isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters (75 feet) for solids.
LARGE SPILL: Consider initial evacuation for at least 250 meters (800 feet) in all directions.
FIRE: If tank, rail tank car or highway tank is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions. (ERG, 2024)
Firefighting
SMALL FIRE: Water spray or fog is preferred; if water not available use dry chemical, CO2 or regular foam.
LARGE FIRE: Flood fire area with water from a distance. Use water spray or fog; avoid aiming straight or solid streams directly onto the product. Do not move cargo or vehicle if cargo has been exposed to heat. If it can be done safely, move undamaged containers away from the area around the fire.
FIRE INVOLVING TANKS, RAIL TANK CARS OR HIGHWAY TANKS: Fight fire from maximum distance or use unmanned master stream devices or monitor nozzles. Cool containers with flooding quantities of water until well after fire is out. ALWAYS stay away from tanks in direct contact with flames. For massive fire, use unmanned master stream devices or monitor nozzles; if this is impossible, withdraw from area and let fire burn.
Non-Fire Response
ELIMINATE all ignition sources (no smoking, flares, sparks or flames) from immediate area. Keep combustibles (wood, paper, oil, etc.) away from spilled material. Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Keep substance wet using water spray. Stop leak if you can do it without risk.
SMALL SPILL: Pick up with inert, damp, non-combustible material using clean, non-sparking tools and place into loosely covered plastic containers for later disposal.
LARGE SPILL: Wet down with water and dike for later disposal. Prevent entry into waterways, sewers, basements or confined areas. DO NOT CLEAN-UP OR DISPOSE OF, EXCEPT UNDER SUPERVISION OF A SPECIALIST. (ERG, 2024)
Protective Clothing
RECOMMENDED RESPIRATOR: Where the neat test chemical is weighed and diluted, wear a NIOSH-approved half face respirator equipped with an organic vapor/acid gas cartridge (specific for organic vapors, HCl, acid gas and SO2) with a dust/mist filter.
Prior to working with Di-Tert-Butyl Peroxide you should be trained on its proper handling and storage.
Di-Tert-Butyl Peroxide is a STRONG OXIDER and is HEAT and SHOCK sensitive.
Di-Tert-Butyl Peroxide must be stored to avoid contact with REDUCING AGENTS; ORGANIC MATERIALS; ETHYLENE DICHLORIDE; STRONG ACIDS (such as HYDROCHLORIC, SULFURIC and NITRIC); POWDERED METALS; METAL SALTS; and STRONG BASES (such as SODIUM HYDROXIDE and POTASSIUM HYDROXIDE) since violent reactions occur.
Sources of ignition, such as smoking and open flames, are prohibited where Di-Tert-Butyl Peroxide is used, handled, or stored.
Metal containers involving the transfer of Di-Tert-Butyl Peroxide should be grounded and bonded.
Use only non-sparking tools and equipment, especially when opening and closing containers of Di-Tert-Butyl Peroxide.
Wherever Di-Tert-Butyl Peroxide is used, handled, manufactured, or stored, use explosion-proof electrical equipment and fittings.
Store in tightly closed containers in a cool, well-ventilated area away from HEAT.
Precautions
Unless a less toxic chemical can be substituted for a hazardous substance, Engineeringcontrols are the most effective way of reducing exposure. The best protection is to enclose operations and/or provide local exhaust ventilation at the site of chemical release. Isolating operations can also reduce exposure. Using respirators or protective equipment is less effective than the controls mentioned above, but is sometimes necessary.
In evaluating the controls present in your workplace, consider:
(1)How hazardous the substance is, (2) How much of the substance is released into the workplace and (3)Whether harmful skin or eye contact could occur. Special controls should be in place for highly toxic chemicals or when significant skin, eye, or breathing exposures are possible.
In addition, the following controls are recommended:
Good Work Practices can help to reduce hazardous exposures. The following work practices are recommended:
Workers whose clothing has been contaminated by Di-Tert-Butyl Peroxide should change into clean clothing promptly.
Contaminated work clothes should be laundered by individuals who have been informed of the hazards of exposure to Di-Tert-Butyl Peroxide.
Eye wash fountains should be provided in the immediate work area for emergency use.
If there is the possibility of skin exposure, emergency shower facilities should be provided.
On skin contact with Di-Tert-Butyl Peroxide, immediately wash or shower to remove the chemical. At the end of the workshift, wash any areas of the body that may have contacted Di-Tert-Butyl Peroxide, whether or not known skin contact has occurred.
Do not eat, smoke, or drink where Di-Tert-Butyl Peroxide is handled, processed, or stored, since the chemical can be swallowed. Wash hands carefully before eating, drinking, smoking, or using the toilet.
