CONDITIONS ON PHYSICAL-TECHNICAL FOUNDATIONS TO ASSURE SAFETY IN THE PRODUCTION AND TRADING OF INDUSTRIAL CHEMICALS

Article 4. Safety assurance in chemical production and trading

Industrial chemical producers and traders must satisfy the conditions on workshops, warehouses, equipment, vehicles and safe operation under the Law on Chemicals; Articles 5, 6 and 7 of this Circular; Vietnam standard TCVN 5507:2002 Hazardous chemicals - Safety rules in production, trading, use, preservation and transportation; and current relevant laws, standards and technical regulations.

Article 5. Conditions on workshops and warehouses

1. Locations

a/ Workshops and warehouses must be located in places suitable to planning conditions:

b/ Locations of chemical production workshops must be convenient for electricity and water supply, water drainage, pollution treatment and transport;

c/ Chemical workshops and warehouses may not be located close to residential areas. For chemical warehouses located within workshops to serve production, their locations must satisfy chemical preservation technology requirements. Chemical warehouses must be placed outside production workshops:

d/ Warehouses must ensure easy access for vehicles and fire engines.

2. Arrangement of workshop and warehouse ground areas

The ground planning for workshops and warehouses must ensure designing standards based on current Vietnamese construction regulations and standards regarding climate, hydrogeology, hydrometeorology, earthquake zoning, fire and explosion prevention and fighting, environmental protection and labor safety:

a/ On workshop ground areas, rational work items with clear functions must be arranged;

b/ Workshop area must satisfy current requirements on arrangement of production equipment;

c/ Production workshop designs must ensure that the indoor working environment reaches the Health Ministry's standards on temperature humidity and wind speed;

d/ In-workshop passages must be arranged rationally for safe transportation within workshops and for fire fighting. Workshops must have walls separating them from the outside;

e/ The designing of chemical warehouses must observe safety rules, reducing to the utmost fire or spill risks and ensuring separation of substances that may cause chemical reactions;

f/ Warehouses shall be designed depending on types of chemicals to be preserved and classified by explosion, tire-explosion and fire risks as specified in Vietnam standard TCVN 2022:1995. Such designing must comply with Vietnamese construction regulations and relevant standards. hi addition to general provisions on work structure, chemical warehouses shall be designed according to fire and explosion prevention and fighting standards regarding tire resistance, fire separation, emergency exit, fire alarm and fighting systems, and fire prevention watch.

3. Structure and arrangement of works

a/ Closed and wide areas must have two-direction emergency exits, which are clearly instructed (in signboards or plans, etc.) and designed to ensure convenient use in emergency cases. Exit doors must be easy to open in the dark or thick smoke;

b/ Warehouses must have open ventilation systems on their roofs, on walls below the roofs or near the floors:

c/ Warehouse floors must be impermeable, even, non-slip and have no cracks for storing leaked water, spilt liquids or contaminated firefighting water or forming surrounding edges;

d/ Warehouse construction and heat-proof materials must be refractory and warehouse frames must be firmly reinforced with concrete or steel.

Article 6. Conditions on equipment

1. Production equipment

a/ Production equipment must satisfy general safety requirements according to current Vietnam standards;

b/ Production equipment must be regularly maintained and cleaned;

c/ Their technical parameters must be inspected and there must be safety systems for their users.

2. Safety equipment and facilities

a/ Lighting facilities and other electric equipment must be installed at necessary places. Temporary installation is disallowed. All electric equipment and facilities must be earthed and have a circuit breaker to operate upon electricity leakage and prevent overload:

b/ Refractory materials must be used for solvent storage places with low ignition temperature or line chemical dust;

c/ Sufficient equipment and instruments must be furnished at chemical production and trading establishments to respond to incidents. Fire warning and fighting systems must be installed at appropriate places and regularly inspected to ensure their readiness for use.

3. Emission and waste treatment systems

a/ Chemical workshops and warehouses must not emit into the air hazardous substances, cause noise or other harmful elements in excess of the current prescribed levels regarding environmental sanitation. Chemical workshops' and warehouses' emissions must satisfy QCVN 19:2009/BTNMT - National technical regulation on industrial emissions for dust and inorganic substances: QCVN 20;2009/BTNMT - National technical regulation on industrial emissions for some organic substances; and QCVN 21:2009/BTNMT -National technical regulation on industrial emissions from production of chemical fertilizers;

b/Chemical workshops and warehouses must have wastewater treatment systems. Treated wastewater must satisfy QCVN 07:2009/ BTNMT - National technical regulation on hazardous waste limits; QCVN 24:2009/ BTNMT - National technical regulation on industrial wastewater; and QCVN 25:2009/ BTNMT National technical regulation on wastewater of solid waste landfills:

c/ Chemical workshops' and warehouses' solid wastes must comply with the Government's Decree No. 59/2007/ND-CP of April 9. 2007. on management of solid wastes. Chemical workshops and warehouses must have tools for collecting and transporting solid wastes out of production zones after each production shift. Waste storage places must be closed and isolated from production zones.

Article 7. Conditions on vehicles and safe operation

1. Chemical vehicles must satisfy current technical standards on hazardous goods to be transported and the following requirements:

a/ Vehicles are designed to prevent leakage or dispersion of chemicals into the environment.

During transportation, chemicals which can cause reactions may not be stored together to avoid danger:

b/ Chemicals must be stored in appropriate packings and transported by special-use vehicles:

c/ Vehicles must bear warning and caution signs. When a vehicle transports different chemicals, the symbols of all chemicals must be stuck on both sides and the rear of the vehicle.

2. Safe operation at chemical warehouses

a/ Chemical production establishments and chemical warehouses must have measures or plans to prevent: and respond to chemical incidents:

b/Chemical production establishments must have internal rules on chemical safety and caution systems suitable to the level of danger of chemicals. For a chemical containing different hazardous properties, the caution sign must sufficiently express such properties;

c/ Operation at chemical warehouses must comply with strict safety and sanitation requirements to avoid such possible risks as fire or leakage:

d/ Warehouse keepers must apply instructions on chemical safety cards of all chemicals stored and transported: instructions on safety and sanitation; and instructions upon occurrence of incidents;

e/ In a warehouse, hazardous substances must be placed separately from areas where people regularly enter and exit: there must be spaces between walls and chemical bales nearest to the walls, and internal passages which are airy and accessible to inspection and fire fighting equipment.
