Final answer:
Repair garages must be adequately ventilated according to the International Mechanical Code to ensure safety from toxic fumes and provide the necessary air exchange.
Step-by-step explanation:
The question relates to the standards for ventilation in repair garages, which must be designed and constructed according to specific codes in order to ensure a safe working environment. Repair garages handle numerous chemicals and substances that can be harmful if not properly vented. According to the International Mechanical Code, repair garages shall be adequately ventilated to remove toxic fumes and provide a safe amount of air exchange.
Proper ventilation in repair garages is crucial due to the presence of vehicle exhaust, which contains carbon monoxide, a potentially deadly gas, along with other hazardous substances. The International Mechanical Code specifies the minimum requirements for mechanical systems, including ventilation systems, to safeguard against health hazards and to promote the welfare and safety of building occupants.
