Where the PEL (Short Term) of a toxic substance is not specified in the First Schedule, the PEL (Short Term) of the substance shall be deemed to be exceeded if the time weighted average concentration of the substance measured over a 15-minute period during any working day exceeds 5 times the PEL (Long Term) of that substance as specified in that Schedule.
Where there is exposure to more than one toxic substance at the same time and the substances have similar harmful effects, the permissible exposure level shall be deemed to have been exceeded if the sum of the ratios between the time weighted average concentration and the permissible exposure level of each substance exceeds one.
Hazardous substances
Subject to regulation 44, all hazardous substances in a workplace shall be placed under the control of a competent person who has adequate knowledge of the properties of the hazardous substances and their dangers.
Subject to regulation 44, adequate warning notices in languages understood by all persons at work in a workplace specifying the nature of the danger of the hazardous substances shall be placed —

the warning label contains a warning on the hazards involved in any hazardous substance in the container;
the warning label specifies every precautionary measure, as far as is reasonably practicable, to be taken when dealing with any hazardous substance in the container; (c)the warning label is easily understood by all persons at work in the workplace.
The following are relevant as practical guidance with respect to the requirements for a warning label mentioned in paragraph (2):
any Singapore Standard relating to the classification and labelling of hazardous substances, published by the Enterprise Singapore Board and as in force from time to time, approved by the Council under section 40B(1) of the Act; (b)any other approved code of practice relating to the classification and labelling of hazardous substances.
Safety data sheet
Subject to regulation 44, where any hazardous substance is used, handled or stored in a workplace, it shall be the duty of the occupier of the workplace to —
obtain a safety data sheet of the substance;
assess the information in the safety data sheet and take precautionary measures to ensure the safe use of the substance; and
make available the safety data sheet to all persons at work in the workplace who are liable to be exposed to the substance.
Subject to regulation 44, where any hazardous substance is sold to any person for use in a workplace, it is a duty of the seller, or any agent of the seller who caused or procured the sale, to provide the buyer of the hazardous substance with a safety data sheet that gives accurate and adequate information on the hazardous substance.
