Approved by the order of the Minister of Emergency Situations of the Republic of Kazakhstan of October 29, 2008 No. 189

Requirements of industrial safety in the chemical industry

Chapter 1. General requirements

1. Requirements are intended for application on productions:

1) sulphuric acid (from pyrite, sulfur, the departing sulphurous gases received when roasting sulphidic ores and hydrogen sulfide);

2) ordinary superphosphate;

3) complex fertilizers (ammophos, nitroammofoska, nitrofoska and others);

4) the concentrated fertilizers (double superphosphate, the defluorinated phosphates and whether then);

5) fertilizer grades;

6) extraction phosphoric acid;

7) boric acid;

8) borax;

9) boric fertilizers;

10) fluoric salts (cryolite, fluoric aluminum, fluorsilicate sodium and so on).

2. Designing, construction and reconstruction of productions of the chemical industry is made according to construction regulations and rules. Modification of project and technical documentation is allowed to be performed, in case of approval of developer of the project or the certified organization, in the presence of positive experimental testimony of industrial safety according to the project documentation. The made changes do not influence negatively working capacity and safety of all technological system in general.

3. Designing and operation of auxiliary buildings and rooms (household, public catering, health centers, for cultural servicing and others) are performed in compliance with requirements of construction regulations and rules.

4. Each production has the project documentation.

5. For the operating and again entered productions are developed and affirm: production schedules, regulations on production supervision, liquidation plan of accident, declaration of safety.

6. The fire-fighting equipment contains in good repair, and is located in easily available places. Use of fire-proof stock in the works which are not connected with fire extinguishing is not allowed.

7. For each technological system measures for the maximum decrease in potential of explosion of the technological blocks entering it are provided:

1) prevention of explosions and the fires in processing equipment;

2) protection of processing equipment against destruction and the maximum emission limitation from it combustible or toxic agents in the atmosphere in case of emergency depressurization;

3) exception of possibility of explosions and fires in volume of factory buildings, constructions and outside installations;

4) decrease in weight of effects of explosions and the fires in volume of factory buildings, constructions and outside installations.

8. In places where smoking is authorized, the corresponding posters are hung out.

9. For all explosive, chemical productions measures for prevention of foreign unauthorized intervention in the course of engineering procedures are developed.

10. Floors and platforms in production rooms on which aggressive liquids spill become covered by anticorrosive protection with the device of boards or ramps. Floors of wet departments are carried out with bias to ladder or to sump and have reliable hydraulic isolation.

11. Cleaning of floors is performed with obligatory neutralization of the spilled aggressive liquids.

12. Cleaning and neutralization of the spilled acid is performed by lime (dry cleaning).

13. In rooms with heat-conducting floors (stone, tiled, concrete and others) on permanent workplaces floorings or lattices keep within.

14. Placement of rooms with wet engineering procedures over premises of control center is not allowed to install the ventilating equipment over and under these rooms, except located on zero mark.

15. Control centers processes do not place in rooms with productions in which allocation of harmful and explosive vapors, gases and dust, with productions in which processing equipment with the increased vibration is installed is possible.

Chapter 2. Heating, ventilation, plumbing and sanitary

16. In wardrobe and shower offices radiators are carried out with protection in order to avoid burn of bodies of employees of the organization in shower.

17. For heating of workers in winter time in not heated production facilities (crushing размольное department, warehouses of pyrite, phosphatic raw materials and others) rooms for heating are equipped.

18. Places of possible release of harmful gases and dust are equipped with local shelters (casings) and system of preliminary cleaning to sanitary standards of harmful gases and dust before their emission in the atmosphere.

19. To carry out tool inspection of efficiency of ventilating systems at least once a year, after capital repairs, not reconstruction of ventilating systems.

20. Analyses of air on dust content and gas contamination make according to the schedule approved by the technical lead of the organization.

21. Closing of ventilating latches and shiber, stitched and exhaust openings is not allowed, to stop and turn on fans to persons to whom servicing of ventilating installations is not entrusted.

22. In production rooms where ignition of clothes or chemical burns (are possible in case of emission of flame from furnaces, during the work with acids and alkalis and others), emergency souls and sinks of self-help or bathtub with water and self-help sinks are established. Emergency souls, bathtubs and sinks of self-help connect to economic drinking water supply system and establish on visible easily accessible places at distance no more than 25 m, from the possible centers of defeat. Installation of emergency flourishes in production rooms in which the potassium, sodium and other chemicals decaying with explosion in case of contact with water are applied is not allowed.

23. When carrying out repair work of the kislotoprovod remote from flourishes and fountainlets, the maintenance force has in case of itself bucket with clear water and soda for washing off and the neutralization of acid burned on sites of skin.

24. At cranes of network of production water the texts prohibiting to use this water for economic and drinking needs are hung out.
