Hercules Fire Extinguishers are provided with surface mounted wall brackets, the brackets are to be secured firmly to the wall using a power drill. Ensure that the height of the carrying handle is compliant with the standards before installing.

OPERATION OF FIRE EXTINGUISHER

P.A.S.S technique:

  1. Pull the safety pin
  2. Aim the nozzle at the base of the fire
  3. Squeeze the lever
  4. Sweep from side to side

Fire Extinguishers are designed to be a one-use product. Upon usage, fire extinguishers are to be recharged immediately at an Authorised recharging station. If you “test” a fire extinguisher by activating it, the powder that comes out of the extinguisher will prevent the valve from fully closing, causing the propellent to slowly leak out over a period of time.

INSPECTION OF PORTABLE FIRE EXTINGUISHER

The owner or occupant of a property in which extinguishers are located shall be responsible for such inspection, maintenance and recharging.
Reference: Singapore Standards 578: Section 10.1.2

Frequency of inspection

The extinguishers shall be inspected monthly by the building owner or occupant, or at more frequent intervals
Reference: Singapore Standards 578: Section 10.2.1

(a) Located in its designated place;
(b) No obstruction to access or visibility;
(c) Operating instructions on the extinguisher label are legible and facing outward;
(d) Seals and tamper indicators are not broken or missing;
(e) Determine fullness by weighing or “hefting”;
(f) Examine for obvious physical damage, corrosion, leakage or clogged nozzle;

RECORD KEEPING

Each extinguisher shall have a label securely attached that indicates the month and year the maintenance was performed and shall identify the person and organisation performing the service. The same label shall indicate if recharging/hydrostatic testing was also performed and shall be affixed with a control tag issued by the accredited certification body.

The approved organisation shall obtain such control tags from the accredited certification body that the approved organisation is registered with to carry out such maintenance and servicing of fire extinguishers.

The approved organisation shall keep proper records of the tags and labels affixed to extinguishers on which maintenance works have been carried out.

Such records shall indicate:

All labels and tags affixed to the extinguishers shall have adequate security features, and be tamperproof and waterproof to protect against theft and counterfeiting.
