M2 Exam Dumps - Commercial Mechanical Inspector

For appliances on roofs, ICC access provisions require a level platform at the appliance. The platform must be not less than 30 inches in any dimension . For the choices provided, that makes 30 inches the correct answer, which is Option C .

The IMC requires access openings for fire dampers to be of a size that allows maintenance and resetting of the damper . The code does not set the answer as same-as-duct, half-diagonal, or a universal 12-inch by 12-inch opening. So Option C is correct.

A low-pressure steam heating boiler is defined as a boiler furnishing steam at pressures not exceeding 15 psi . That matches Option B .

Under the IMC ventilation table, locker/dressing rooms and sports locker rooms are identified with required mechanical exhaust, while spaces such as guard stations do not carry that same exhaust requirement in the table. A high school locker room falls within the locker-room/sports-locker-room category, so Option C is the correct answer. Gambling casinos and office break rooms are provided outdoor air rates, but they are not the required-exhaust space among these listed choices.

The IMC prohibits energy recovery ventilation systems in several applications, including hazardous exhaust systems , smoke control systems , commercial kitchen exhaust systems , and clothes dryer exhaust systems . Equipment intended to assist with occupant evacuation falls under smoke-control/life-safety type applications and is not an allowed ERV use. By contrast, systems utilizing coil-type exchangers are the exception among the listed choices because they are not one of the prohibited applications in this question. Therefore, Option A is correct.
