Kitchen hoods need to be checked regularly to make sure they work well in case of a fire, just like any other fire suppression system. If you have a commercial kitchen, you’ll want to make sure that your fire suppression system is ready to go so that your building doesn’t catch fire and cause a lot of damage.
Why Do I Need an Inspection?
In a commercial kitchen, preventing fires should be a top priority. One way to do this is to have your hood inspected, tested, and serviced regularly. Regular inspections of your system will:
- Make sure the fire suppression system is ready to go in case of a fire;
- Stop unintended discharge;
- Give you peace of mind that your kitchen is safe;
- Make sure fire code and insurance requirements are met;
- Keep you from getting fined for not following code.
The NFPA says that kitchen hood suppression systems must be checked by a certified professional every six months. During a typical inspection of a kitchen hood, these things are done:
- Check nozzle and conduit locations.
- Make sure pipes are tight and secure.
- Clean nozzles.
- Check pressured cylinder gauges and hydrostatic test dates.
- Test the manual pull station.
- Cut a terminal test link to make sure the automatic actuation cycle works.
- Make sure electricity and gas are turned off when the system turns on.
- Replace any parts that need it, such as center link housings, system cartridges, and fusible links.
- How well electrical interlocks work
- Write down and tell the inspector about any problems that were found.
After a professional does the twice-yearly inspection, you should have paperwork to show that your system is compliant. This includes tagging, keeping track of any repairs, and a report of the inspection.
Only trained professionals should do the inspections every six months, but the building owner is responsible for the monthly visual checks. A visual check of the nozzles, gauges, and tamper indicators is part of these inspections. The building owner should also check for grease build-up in the hood or duct and make sure the pull station is not blocked.
