Organic Peroxide Safety Data Sheets

The Organic Peroxide Safety Data Sheets (SDS) relating to the substance you are storing/using and the labels found on the packaging should explain all of the hazards associated with it. The SDS should, for example, describe the conditions that cause the product to undergo dangerous chemical reactions and it should also provide details of any special storage requirements.

Some organic peroxides have to be refrigerated to reduce the possibility of fire and the refrigeration unit including all electrics should be suitable for use in a hazardous area, carrying ATEX certification. The SDS should outline any minimum temperature under which the product should not be stored. This is critical because crystals of the peroxide may form if it is too low and these crystals could be an explosion hazard as they can be extremely sensitive to shock.

Your Organic Peroxide Safety Data Sheets should comprise 16 sections which cover:

  • SECTION 1 – IDENTIFICATION

Contact details of the person/company responsible for supplying the product, the uses of the product, as well as the telephone number to contact in case of an emergency.

  • SECTION 2 – HAZARD(S) IDENTIFICATION

Classification of the substance or mixture, details on the hazards and the potential effects and symptoms resulting from use. This will help in the assessment of the risks to the health of workers and the environment. The information in this section must be consistent with the information on the label.

  • SECTION 3 – COMPOSITION / INFORMATION OF INGREDIENTS

If the product is a mixture, this section will give information on the hazards of each of the individual substances in the mixture.

  • SECTION 4 – FIRST-AID MEASURES

Describes the necessary first aid measures to be taken and covers: General first-aid measures, first-aid measures after inhalation, first-aid measures after skin contact, first-aid measures after eye contact, first-aid measures after ingestion, most important symptoms and effects both acute and delayed, chronic symptoms, indication of any immediate medical attention and special treatment needed.

  • SECTION 5 – FIRE-FIGHTING MEASURES

Recommendations for fighting a fire involving the product including suitable extinguishing media, protective equipment and chemical hazards from the fire

  • SECTION 6 – ACCIDENTAL RELEASE MEASURES

Appropriate response to spills, leaks or releases, including containment and clean-up

  • SECTION 7 – HANDLING AND STORAGE

Safe handling practices and conditions for safe storage of the product, including any incompatibility issues

  • SECTION 8 – EXPOSURE CONTROLS / PERSONAL PROTECTION

Exposure limits, engineering controls and personal protective measures needed to minimize worker exposure

  • SECTION 9 – PHYSICAL AND CHEMICAL PROPERTIES

Physical and chemical properties associated with the product

  • SECTION 10 – STABILITY AND REACTIVITY

Reactivity hazards and stability information

  • SECTION 11 – TOXICOLOGY INFORMATION

Information regarding toxicological and health effects, or an indication that such data is unavailable

  • SECTION 12 – ECOLOGICAL INFORMATION

Environmental impact of the product if it were to be released in to the environment

  • SECTION 13 – DISPOSAL CONSIDERATIONS

Proper disposal and recycling, or reclamation and safe handling practices

  • SECTION 14 – TRANSPORT INFORMATION

Classification information for shipping and transporting

  • SECTION 15 – REGULATORY INFORMATION

Details relevant EU/national legislation

  • SECTION 16 – OTHER INFORMATION

Relevant information not found elsewhere on the SDS such as; training advice, full text of hazard statements etc.

CHECK

  • Are there 16 sections in your SDS?
  • Is it written in clear and concise English?
  • Is the SDS dated and have revision dates and details of revisions been provided?
  • Do the details on the product’s label exactly match those given in section 2 of the SDS?  Contact the supplier and request an updated version if you aren’t satisfied with the information provided
  • Use the information to prepare risk assessments, inform employees of the hazards and protection measures to be taken when using the product and the measures they should take in an emergency
  • Copies of the SDS for all the products held on site should be readily available to staff working with the product and emergency responders. Apart from the master file, it is good practice to have copies available in the working area and remote from it (at security and or with the site response team) so that the information is readily available at all times.
  • Regularly check the SDS to ensure that all copies are up to date
  • If there is an Exposure Scenario annexed to the SDS, ensure the risk management measures relevant to the use of the substance are in place.
