Random Section of GOST 127.1-93
2. safety Requirements
2.1. Sulphur is combustible. Powder suspended in air is fire-risk and explosive. The lower concentration limit of flame spreading (ignition) is 17 g/m3; temperature of spontaneous ignition is 190°C according to GOST 12.1.041.
Hydrogen sulphide evolved from liquid sulphur explodes under the volume concentration from 4.3 to 4.5%; temperature of spontaneous ignition is 260°C.
2.2. Sulphur is attributed to the 4th class of danger (GOST 12.1.005).
Sulphur causes inflammation of micous tunic of eyes and upper respiratory tract, irritation of integument, disease of gastrointestinal tract; it has no cumulative features.
Hydrogen sulphide is a toxic substance strongly affecting the central nervous system.
Sulphurous anhydride formed during burning of sulphur causes irritation of micous tunic of nose and upper respiratory tract.
Maximum allowable concentration of sulphur in air of working area is 6 mg/m3; maximum allowable concentration of sulphurous anhydride — 10 mg/m3; maximum allowable concentration of hydrogen sulphide — 10 mg/m3.
2.3. Production facilities and laboratories in which sulphur for technical use is processed are to be equipped with combined extract and input ventilation assuring observance of maximum allowable concentrations of toxic substances in air of the working area.
Air in the working area is to be controlled pursuant to requirements of GOST 12.1.005 according to the methods approved by the Health Ministry.
2.4. All workers are to be equipped with special clothes and individual protection facilities in compliance with GOST 12.4.011.
3. Rules of acceptance
3.1. Sulphur is subject to acceptance and delivery tests.
3.2. Sulphur is accepted by lots. Sulphur volume shipped to the same address and accompanied with one quality certificate is considered as a lot.
In case of waterage every transport unit (barge, motor ship, tanker) is considered as a lot.
3.3. The quality certificate is to include the following data:
— name of manufacturing enterprise and/or its trade mark;
— name and kind of product;
— lot number and shipment date;
— numbers of railroad cars or other transportation facilities (in case of direct shipment);
— results of passed tests or confirmation of the fact that a product meets the requirements of this standard;
— net weight;
— 4a danger sign and 4133 classification code according to GOST 19433;
— U.N.O. serial number: for lump sulphur – 1350; for liquid sulphur – 2248;
— signature and stamp of the inspection department;
— name of this standard.
3.4. To control quality of lump and liquid sulphur, samples are selected from every fourth car (tank-car) of the controlled lot, but no less than from three cars (tank-cars).
In case of sulphur shipment by means of less than three transport units, samples are taken from each transport unit.
In case of waterage it is allowed to take samples in the course of loading (unloading) of barges.
