Our work ranges in scope from the supply of simple extinguishers to the design and commissioning of complex multi-site alarm and emergency lighting systems. We run Fire Training courses, provide Fire Risk Assessments and have recently launched a full range of Safety Workwear. Our work takes us across every business sector, from retailing to hi-tech, manufacturing, transport, local authorities, hospitals, schools and airports.

The company operates a quality control system in accordance with ISO9001:2015 for the maintenance of portable fire extinguishers, fire alarms and emergency lighting systems. We were accredited with third party approval in 1994 by the British Standards Institute and our service engineers are all certified through the BAFE Technicians Training Scheme.
Services
We are so confident in the quality of our products that we supply all our extinguishers with warranties ranging from 5 - 10 years. All our fire extinguishers come with a fixing bracket as standard, ready for use. If you're not sure what you are looking for, feel free to give us a call. We stock fire extinguishers for every application so we can be sure to have what you are looking for.
Dry Powder Fire Extinguishers can be used on Class A, B, C and electrical fires and are very quick and effective at putting fires out. You have to be careful the fire is completely put out when using a Powder extinguisher as it only removes the oxygen element from the fire, so the residual heat may re-ignite the fire.
These extinguishers contain CO2 at high pressure and are suitable for Class B fires. They won't damage computers or other electrical equipment and are often sited alongside a water or foam extinguisher to cover the widest range of fire types. If you ever need to put out an electrical fire, remember to turn off the power supply to the equipment to ensure the equipment doesn't re-ignite.
These are specifically designed for use on kitchen fires involving burning mineral oil and deep fat fryers (Class F fires). They work by enabling a layer of chemical foam to be created on top of the fire from a safe distance. They may also be used on Class A fires. Don't attempt to use an extinguisher on a fire unless you feel it is safe for you to do so.
Fire alarms and emergency lighting systems are design to give advance warning of a fire and ensure anyone in the building escapes as quickly and safely as possible. OHeap provides a complete solution for your Fire Alarm and Emergency Lighting requirements, from design and installation to on-going service and 24/7 monitoring.

Positive: Professionalism, Punctuality, Quality
They came to service our care home during the COVID pandemic. The engineer (Daniel Cassidy) was considerate to the circumstances, professional and ensured that our resident's remained safe. He explained in detail his procedure and allowed for any questions. Very happy with the service.

Ordered some boots online on 16.8.20, still waiting!!!
After talking to a manager, it transpired that it was a lack of communication, not the company's, that caused the delay. Today I received my boots, as they had sold out of the ones i has ordered, i received an upgrade. Many thanks, greatly appreciated

Used this place to fill up 2 C02 fire extinguishers that I use to keep plants heathy in my fishtank. I found it very difficult to locate somewhere in Derby to help me out and was very happy when I found this place. They were very helpful, cheap and fast. I would definitely recommend this place to any hobbyist who uses C02 like me, or of course if you need products or advice of fire safety.
