ABCs of Fire Extinguishers

Innovation for safety. The groups defined in European, International and North American standards are fundamentally the same, as illustrated by the following table. Equipment must never be used in an atmosphere capable of ignition at the temperature indicated on the marking temperature class. Manufacturer identification:. A flameproof equipment offers an enclosure in which the parts which can ignite an explosive gas atmosphere can be placed.

It withstands the pressure developed during an internal explosion of an explosive mixture, and prevents the transmission of the explosion to the explosive gas atmosphere surrounding the enclosure. There are two construction values which are essential for a flameproof equipment to answer to the 3 criterias:. These values depend on gas group and the maximum allowed gap depends on the length of flameproof joint. It is necessary to lubricate the thread and to ensure that at least 5 threads are engaged for metric thread and that 5 threads are present on each parts for NPT threads.

Holes which are not used for cable entries must be blanked using the appropriate blanking plugs. The equipment is supplied with the lubricated joint. When the equipment is installed, the path must be lubricated to keep them in good condition. Use a non-hardening, anti-corrosive grease see technical note. Method of protection applicable to electrical equipment such as light fittings, sockets, switches, etc, which consists of preventing the occurrence of any accidental ignition.

The construction principles for increased safety « e » equipment are as follows:. These principles are respected by screwing the cable gland directly onto the enclosure or, for untapped holes, by fixing with a locknut. The equipment has a protection level of at least IP 54; it is therefore important to ensure that the sealing joint is in good condition when the product is installed.

It is important to be sure that the gasket is properly positioned for the plugs and sockets and for all the luminaries before connecting the male and female parts for plugs and sockets and before closing the light transmitting part of the lighting fixture. For the connection, all technical note or instruction sheet shall be followed. Except «Ex d» enclosure, equipment having a combined protection type « d » and « e » are the most commonly used.

Some apparatuses such as power sockets, lampholders, etc, which create arcs and sparks in normal operation, cannot be designed only with protection mode «e». The connection of cables to the electrical equipment shall maintain the explosion protection integrity of the relevant type of protection. Electrical installations for explosive atmosphere must comply with the requirements regarding installations in both non hazardous and hazardous locations:.

Hazard Labelling Symbol – Class 1- Explosive Div. 1.4 – D

In our RCRA training programs, we provide information about the different hazard classes and their divisions, each division has a specific definition of what constitutes that type of material. A material may meet the defining criteria for more than one hazard class but is assigned to only one hazard class. The nine 9 hazard classes, numbered , are defined at 49 CFR Part Of these nine classes, some are further broken down into divisions.

Class 1 Explosive 1.1D Hazard Warning Diamond Placard – Code J001D/PL

Use the form below to search for your specific query. A Class D fire is characterised by the presence of burning metals. Only certain metals are flammable and examples of combustible metals include sodium, potassium, uranium, lithium, plutonium and calcium, with the most common Class D fires involve magnesium and titanium. Although it usually takes extreme heat to ignite metal, once a fire has been ignited it can very quickly and very easily spread and develop, making them incredibly dangerous and destructive. Alternatively, sodium is a highly reactive element which immediately burns when in contact with air or water, resulting in explosions and making it particularly hazardous. This includes things such as laboratories, warehouses and factories and anywhere which uses manufacturing processes to cut, drill or mill metals.

Class 1-1.6 Explosive UN Hazard Warning Diamond
