Organic Peroxide Purchasing Principles

1. Organic peroxide users should purchase organic peroxides from qualified suppliers and ask for commodity invoices.

2. The organic peroxide user should ask the supplier for the chemical safety data sheet (SDS) and safety label consistent with the purchased organic peroxide.

3. The organic peroxide user should ask the supplier for the organic peroxide composition test report, and the relevant test results should comply with the provisions of the United Nations “Recommendations on the Transport of Dangerous Goods – Model Regulations” (21st Revised Edition).

4. The organic peroxide packaging purchased by the organic peroxide user unit shall comply with the provisions of GB/T 27833.

5. Communication of safety information

(1) The organic peroxide user unit shall communicate the relevant safety information of the organic peroxide to the safety management personnel and relevant on-site operators.

(2) The organic peroxide user should communicate the emergency response procedures for the organic peroxide accident to the safety management personnel and relevant on-site operators.

6. Storage requirements of the user unit

(1) Organic peroxides should be classified and stored in special warehouses and special storage cabinets.

(2) The special warehouse for organic peroxides should meet the following requirements:

a) Set according to the provisions of GB 50016 (for explosive organic peroxides, set according to the provisions of GA 1511);

b) Set up hazardous chemical safety signs, hazardous chemical safety notice cards, chemical safety data sheets (SDS), and handling procedures as required;

c) The in-out and out-of-warehouse management of organic peroxides should be connected to the intelligent traceability system (APP) for hazardous chemicals, and the in-out and out-of-warehousing situations are automatically recorded by manual scanning to prevent loss;

d) Organic peroxides shall be stored in accordance with the standard division and classification, and shall not be stored in excess or in excess varieties. The packaging of organic peroxides stored in isolation in the same warehouse shall be affixed or attached with chemical safety labels consistent with the items in the package; Organic peroxides are strictly prohibited

(replacement) loading, splitting, unpacking (bags), barrels (bottles) and deployment operations;

e) When storing liquid organic peroxides, facilities should be set up to prevent liquid from spreading, and facilities made of glass-lined, polyethylene and other materials should be used;

f) Follow the principle of “first in, first out”. When handling and storing organic peroxides, avoid being upside down and falling, and cannot give shocks; the packaging containers of organic peroxides should be upside down, and cannot be placed horizontally or upside down;

g) The organic peroxide user should conduct regular inspections of the warehouse, and if the packaging of organic peroxide is found to be leaking or swollen, the organic peroxide must be removed or the normal packaging must be replaced;

h) The warehouse shall be equipped with emergency equipment such as fire extinguishers, fire blankets, absorbents (such as vermiculite), and personal protective equipment such as gas masks and protective clothing as required.

(3) The special warehouse for temperature-controlled organic peroxides shall meet the requirements of 6.4.2, as well as:

a) For organic peroxides whose storage temperature is ≥35°C or control temperature (TC) ≥50°C, comprehensive management should be carried out in combination with the product safety data sheet (SDS); for organic peroxides whose storage temperature is <35°C or controlled If the temperature (TC) is less than 50°C, “dual refrigerators and dual power supplies” should be set up (one for use and one for standby, where the power supply should be a diesel generator set);

b) For the storage of organic peroxides requiring temperature control (cooling), a mechanical device for active cooling shall be provided;

c) It should be equipped with a temperature monitoring and alarm system, using two-point temperature measurement (the highest temperature as the management temperature), setting temperature control alarms, critical temperature alarms, door opening alarms, and alarms when people are trapped by mistake;

d) The organic peroxide user should monitor the temperature and humidity in the warehouse on a daily basis, keep the temperature and humidity within the specified range, arrange personnel on duty 24 hours a day, and deal with equipment failures in time.

(4) The requirements for special storage cabinets for organic peroxides should be met.

a) If the organic peroxide user uses a small amount of organic peroxide and does not have the conditions to set up a special warehouse for hazardous chemicals or a special intermediate warehouse, it should set up a special storage cabinet for organic peroxide in the factory area or warehouse;

b) The special storage cabinet should be set on a site with a flat ground and a relatively fixed position, and there is no open flame or heating equipment around;

c) The cabinet body of the special storage cabinet should ensure that the static grounding is good, and the surrounding electrical facilities meet the explosion-proof requirements; the special storage cabinet for storing liquid organic peroxides should be equipped with an anti-leakage collection tank; the special storage cabinet for storing organic peroxides sensitive to impact Anti-impact fireproof foam should be set inside;

d) The internal material of the special storage cabinet should be made of durable materials (glass-lined, polyethylene, etc.); the special storage cabinet should be provided with exhaust holes, which should be open and the outside should not be blocked;

e) The special storage cabinet should be equipped with an automatic temperature warning and remote alarm system and have on-site acousto-optic alarm and automatic alarm function of the system center console or the intelligent traceability system (APP) for hazardous chemicals when the temperature exceeds the temperature; the special storage cabinet should be connected to hazardous chemicals Product intelligence traceability system (APP), manually scan the code to automatically record the in and out of the warehouse to prevent loss;

f) The special storage cabinet should use a sealed container to contain organic peroxides, and the packaging should be affixed with easily identifiable safety labels and traceability barcodes, and items that are contraindicated with organic peroxides should not be stored;

g) It is forbidden to carry out sub-packing (replacement), disassembly, unpacking (bags), barrels (bottles) and deployment operations in special storage cabinets;

h) Hazardous chemical safety signs, hazardous chemical safety notification cards and chemical safety technical specifications (SDS) shall be posted on or near the outside of the special storage cabinet;

i) Emergency equipment such as dry powder fire extinguishers, fire blankets, and absorbents (such as vermiculite) should be installed near the special storage cabinet.
