What safety features must be present in the machine room?

The correct answer highlights the necessity of having multiple safety features in the machine room, specifically proper ventilation, fire protection systems, and emergency lighting. Each of these elements plays a critical role in ensuring a safe working environment.

Proper ventilation is essential for maintaining air quality in the machine room. It helps to dissipate heat generated by machinery and prevents the accumulation of harmful gases that could endanger workers’ health.

Fire protection systems are crucial for detecting and responding to fire hazards. These systems can include fire alarms, sprinklers, and other mechanisms designed to suppress or mitigate fires. Given that machines often generate heat and may present flammable materials, having an effective fire protection system can significantly reduce the risk of a fire turning catastrophic.

Emergency lighting is vital for ensuring safety in the event of a power failure or other emergencies. It provides illumination when regular lighting is compromised, helping personnel to navigate safely out of the machine room, particularly in potentially hazardous situations.

By incorporating these three safety features, a machine room can operate more safely and effectively, protecting both personnel and equipment. This comprehensive approach to safety aligns with industry standards and regulations, making it the correct choice.
