SAFETY RULES FOR SCHOOLS ON COMPRESSED GAS CYLINDERS
*****
SCIENCE TEACHERS AND LABORATORY TECHNICIANS SHOULD PAY SPECIAL ATTENTION TO THE PROPER USE AND STORAGE OF COMPRESSED GAS CYLINDERS IN SCHOOLS.
+THIS IS NECESSARY IN VIEW OF THE INCREASING USE OF SUCH GAS CYLINDERS AS SOURCES OF GAS SUPPLY IN SCIENCE LABORATORIES IN SCHOOLS, AN EDUCATION DEPARTMENT SPOKESMAN SAID.
THE USE OF COMPRESSED GAS CYLINDERS SHOULD BE RESTRICTED TO THE SCHOOL SCIENCE LABORATORIES AND UNDER THE SUPERVISION OF SCIENCE TEACHERS AND LABORATORY TECHNICIANS WHO KNOW THE NATURE OF THE GASES AND THE PROPER HANDLING OF THESE CYLINDERS, HE SAID.
EACH SCHOOL IS ALLOWED TO STORE A CERTAIN AMOUNT OF COMPRESSED GAS CYLINDERS AND BE EXEMPTED FROM LICENSING, AND THE MAXIMUM QUANTITY IS TWO CYLINDERS OF OXYGEN, AND ONE EACH OF NITROGEN, CARBON DIOXIDE AND HYDROGEN.
SAFETY PRECAUTIONS REGARDING STORAGE SHOULD ALSO BE OBSERVED, THE SPOKESMAN SAID.
COMPRESSED GAS CYLINDERS SHOULD BE STORED IN A COOL PLACE AND PROTECTED FROM DIRECT SOURCES OF HEAT, AND SHOULD NOT BE STORED ABOVE OR NEARER THAN TWO FEET FROM ANY BURNER.
THEY SHOULD BE STORED RESTING ON THE FLOOR OR ON SPECIALLY CONSTRUCTED STANDS ON THE GROUND. THEY SHOULD NOT BE STORED IN ANY COMMON PASSAGEWAY, AND SHOULD NOT BE STORED BELOW GROUND LEVEL OR IN ANY PLACE WITHOUT ADEQUATE VENTILATION.
