What are the main NFPA standards applicable to manufacturing companies in Quebec?

NFPA 30: Flammable and Combustible Liquids Code

This standard defines safety requirements for the storage, handling and transport of flammable or combustible liquids. It is adopted by the Regulation respecting occupational health and safety. Manufacturing companies that use and store flammable solvents, fuels and chemicals must ensure that their facilities comply with this standard in order to minimize the associated risks.

NFPA 33: Standard for spray application using flammable or combustible materials.

This standard defines the requirements in order to mitigate the risks of fire and explosion in the context of paint, coating and powder application processes. With the exception of acrylic paints and other water-based coatings, the majority of paint shops use paints based on solvents or combustible powders. Paint booths, as well as related systems such as their ventilation, rooms for mixing, drying parts, cleaning guns and recovering solvents, are particularly vulnerable to the risk of fire and explosion. NFPA 33 is adopted by the CNPI and commonly used by competent authorities to judge the compliance of paint shops.

NFPA 61, 484, 652, 654, 664: Combustible Dust Standards

These standards define the requirements for the prevention of fires and explosions related to the problem of combustible dust. Most processes dealing with materials as varied as flour, sugar, food products, wood, paper, plastic and even metals, produce dust that can cause a risk of deflagration when sufficiently fine and suspended in the air. Manufacturing industries, on the other hand, produce dust through machining. NFPA standards related to combustible dust issues are adopted in whole or in part by applicable codes and regulations. Currently, the NFPA organization is working to consolidate the existing documents into a single standard, NFPA 660.

NFPA 68: Standard for Protection by Explosion Release Devices

This standard defines the acceptable design and calculation methods for protecting a volume, whether it is equipment or a building, using an “explosion release device”. Commonly referred to as an explosion vent, this device works by releasing the pressure caused by an explosion of combustible dusts, flammable gases or vapours.

NFPA 69: Standard for Explosion Prevention Systems

Complementary to NFPA 68, this standard includes design, installation, maintenance and testing criteria for active explosion prevention, containment and bypass systems, as well as passive isolation systems.

NFPA 13: Standard for Sprinkler Installation

A reference adopted by the NFC for the design and installation of automatic sprinkler systems, NFPA 13 deals with approaches to the design of sprinkler systems, the installation of the system, in order to effectively prevent injuries and property losses.

In conclusion, NFPA standards are many and varied

In all, there are over 300 NFPA standards. These standards cover a wide range of topics including fire and explosion protection, chemical and electrical safety. These standards are also constantly updated and revised on a regular basis to take into account security best practices and the latest technologies. To see clearly, it is important to consult an expert in fire-explosion safety.
