17
Q

it detects larger smoke particles from slow-burning fires, producing reliable results with few-false positives, and are more expensive but more accurate that ionisation detectors.

A

photoelectric (optical) alarms

18
Q

These are recommended for all rooms, except kitchens, due to their sensitivity to various fires, faster response, and reduced false alarms compared to single sensor alarms.

A

ionisation/photoelectric (multi-sensor) alarms

19
Q

it sensed temperature changes and are non-smoke-sensitive, detecting fires faster than smoke detectors, ideal kitchens, garages, and lofts, they reduce false alarms.

A

Heat detectors

20
Q

It is crucial for home and workplace use, preventing accidents and injuries, protective equipment, especially in construction and maintenance industries, has evolved over time.

A

electrical safety

21
Q

it is crucial in both work and home settings, as thousands of people die annually due to fires , proper protection and fire fighting equipment ensure maximum protection and safety for firefighters

A

fire safety

22
Q

it is crucial for businesses and homes alike, protecting against fires and ensuring safety for both small and large business.

A

fire extinguisher

23
Q

It is a fully fire protection system’s primary component . It alerts in case of a fire and directs you to the fire’s exact location

A

Fire alarms

24
Q

It release constant, intense water upon a fire alarm, effectively preventing major fires in numerous instances.

A

fire sprinklers

25
