A sprinkler system is an active fire defense system consists of pipes that are connected to a water supply. The system is designed to automatically discharge water over areas affected by fire. There are four different types of sprinkler systems: Wet System (make it link that will take to another page) Dry System Pre-action Deluge It is important to maintain these systems in good working condition to protect people and property; therefore, NFPA 25 and BC Fire Code 1998 6.5.1. sets the rules for inspection, maintenance and testing of sprinkler systems. Benefits of using our Service You get your sprinkler systems inspected, tested and maintained by certified and experienced technicians. We will be a phone call away from you for 24/7. Providing inspection, maintenance, replacement and repair of your sprinkler system. We will call you and remind you before the due date to insure your sprinkler system tested and inspected before current inspection expires. We will provide winterization of your dry sprinkler system to prevent freeze damage. Every customer, with dry sprinkler systems, will be contacted by us to book for winterization before winter starts. Every 3 year, our customers will be informed by us to get 3 year full flow done. Click for more information.
Winter is right around the corner and your dry sprinkler system can be vulnerable to cold weather. The common question we get from our customers is “why do I need winterization for a dry sprinkler system?” Water vapor develops inside the sprinkler pipes throughout the year resulting in condensation that could cause water accumulation at low points of dry sprinkler systems. When the temperature hits 0 celsius, water will freeze and crack the pipe. Loss of air from the cracked pipe will cause air pressure changes in the system then the system will flood with water. It will result in severe damage to the sprinkler system as well as your property.
You need winterization if you have the following:
- Dry Sprinkler system or low point of your system in unheated area.
- The weather can get below 0 celsius.
If your system is in a heated area, you need to inspect the building to make sure there is no broken windows or wall cracks that a draft could enter through.
Backflow Preventer Inspection
Backflow devices are installed onto plumbing systems to safeguard of our city water supply. It prevents intoxicated water from flowing back into the city water. Our water supply from the city normally has certain pressure to facilitate water to flow from the tab; however, sometimes this pressure could decrease, which could result in backflow of contaminated water to the city water.
In case of failed device, our technicians will perform repair of the certain device. Backflow devices can be costly; hence, we employ highly experienced technicians who could repair failed backflow devices.
Fire Extinguishers
A fire extinguisher is one of the first defensive fire protection device used to put out small fires that are in beginning stage. Most of fires are small at inception and can be extinguished by the fire extinguishers; therefore, these devices must be handy in residential and commercial properties.
NFPA 10 sets up the obligation to ensure that fire extinguishers will be in good working condition at all time to provide “first line of defense” against small fires. The provision states installation. inspection, maintenance and selection of correct type of fire extinguisher. Because fire extinguishers play significant role in fire protection; their functioning, when needed, depends on some conditions. Please refer to NFPA 10 for further detail. Annual maintenance and inspection of fire extinguisher are required by NFPA 10.
Fire extinguishers are required 6 and 12 years mandatory maintenance servicing. K Class and Co2s are every 5 year.
6 year maintenance
When a fire extinguisher due for 6 years, we remove the content and refilling it along with full internal and external inspections. Once the bottle is refilled, it is pressurized by nitrogen gas.
Hydrostatic Testing
Hydrostatic testing is required every 12 years from manufacturing date of the ABC dry chemical extinguisher. Hydrostatic test of Co2 and K class extinguishers are required every 5 years.
Types of Fire Extinguishers
There are five different types of fire extinguishers depending on fuel type:
- Class A: Ordinary combustibles such as paper, trash and wood.
- Class B: Flammable Liquids such as oils, gasoline and paints.
- Class C: Electricity. This is for types of fire that any live electrical equipment is involved.
- Class D: Combustible Metals. Any type of metal is involved.
- Class K: Cooking materials such as grease,cooling oils and fat.
It is important to use correct type of fire extinguisher. Using wrong type of extinguisher could make the fire worst. The most common fire extinguishers are ABC Dry Chemical, K Class and CO2s. ABC Dry Chemical fire extinguishers are multi purpose extinguishers that can be used to extinguish Class A, B and C fires. K Class extinguishers are for Class K fires, and are used in restaurants where there is a kitchen exists.
Need to be Trained?
Most people do not know how to use a fire extinguisher. We do provide free fire extinguisher training for your employees during your annual inspection. Any other time, hourly labour rate will apply.
