Study Notes
Ventilation in Factories
- In cases where meeting ventilation opening requirements is impossible due to adjacent buildings and height, the Inspector may order the manager to provide additional ventilation using roof ventilators or mechanical means.
- Mechanical ventilation must supply at least six times the cubic capacity of the workroom in an hour, distributed evenly without dead air-pockets or undue draughts.
Special Climate Conditions
- In regions where outside air temperatures exceed 35°C with a wet-bulb temperature of 25°C or below (15th March-15th July), the Inspector may order the manager to cool outside air by passing it through water sprays using unit-type evaporative air coolers or central air washing plants.
Rules for Safety Officers
- A safety officer must be conversant with hazardous properties of chemicals, their permissible limit values, and certification of safety in working in confined spaces.
- They must also be familiar with current techniques of sampling and analysis of environmental contaminants and able to arrive at a reliable conclusion regarding safety.
Qualifications for Ventilation System Designers
- A designer must have a degree in Mechanical or Electrical Engineering or equivalent and at least 7 years of experience in designing, fabricating, installing, testing ventilation systems, and other ancillary equipment.
