Examples of explosion parameters: Explosion pressure and explosion severity The dust explosion classes are the basis for designing constructive Many factors influence the risks from a fire involving dangerous substances. Most manufacturers of industrial HVAC equipment make air-conditioning and ventilation products for light industrial or milder conditions. Explosion-proof devices must be used in plants where potentially explosive atmospheres are likely to occur. GFCI where required. An explosion-proof motor has several important characteristics. Denotes temperature classification (see temp classification for alternatives) EPL - Equipment Protection Level (see EPL table for . Explosion proof rated equipment is constructed so that it cannot set off an explosion when surrounded by specified flammable gases or dust. 2 Several of these standards are: CAN/CSA C22.2 No.157-92 - Intrinsically Safe and Non-Incendive Equipment for Use in Hazardous Locations CAN/CSA E60079-11:02 - Electrical Apparatus for Explosive Gas Atmospheres - Part 11: Intrinsic Safety "i" FM 3610 - Intrinsically Safe Apparatus and Associated Apparatus for Use in Class I, II, and III, Division 1, Class I, Division 1, Groups A, B, C and D, and class II, Division 1, Groups E, F, and G, in accordance with the National Electrical Code (NEC), NFPA 70. Even slight damage to a flame path can permit burning gases to escape, igniting the surrounding atmosphere. 1 & 2, Groups B, C, D; Class II, Div. Rugged, reliable electrical connectivity for hazardous locations. Specific marking for explosion protection Equipment group (Could be I for mining or II for surface industry) . And simply because a motor operates in a hazardous location, the motor is not necessarily explosion-proof.

Determine the appropriate protection concept : Intrinsic safety, flameproof, etc. Their constructive measures prevent the occurrence of ignition sparks or hot surfaces. 1 & 2, Groups E, F, G . The International Electrotechnical Commission publishes the 60079 series of standards which defines a system for classification of locations, as well as categorizing and testing of equipment designed for use in hazardous locations, known as "Ex equipment". The company vacated the building, moved out computer equipment, however the battery back-up system was left behind. These specifications are complex and every country insists on making their own rating system. A distinction needs to be recognized between equipment designed to comply with We need to take photographs within that area to document equipment during normal operation. Includes aluminum, magnesium, and other metals with similar natures. Group is divided in three groups where Group I is reserved for mining locations. All Explosion-Proof motors are supplied with Explosion-Proof UL and CSA approved conduit boxes as standard. NFPA 484, Standard for Combustible Metals, 20122015 edition. Class 2, Division 1 & 2. We recommend electrical enclosures meet or exceed a NEMA rating of Type 4 or Type 4X for use in a Class1 Div2 hazardous location when used with appropriate purge systems. Explosion-proof enclosures are designed so that escaping gases will be sufficiently cooled as they exit through openings that are long in proportion to their width. 06/10/2019. Group. NEMA Ratings. Type 7: Explosion-proof. It is defined as the primary origin in the deviation point of the pres-sure/time curve and used as parameter Kst-value for classification into dust explosion classes St 1, St 2 and St 3. This quick guide breaks down what qualifies as an explosion-proof motor, outlines the various classifications for hazardous locations, and provides a simple five-step approach for choosing the best motor to meet specific application needs. NEMA Type 4 Enclosures are intended for indoor or outdoor use primarily to provide a degree of protection against windblown dust and rain, splashing water, hose directed water . Group F.

Requires explosion-proof design and a safety shutdown system, as well as intake flame arrest and an exhaust system spark arrest system. The Zone system of hazardous area classification, defines the probability of the hazardous material, gas or dust, being present in sufficient quantities that can generate explosive or ignitable mixtures. Class I Zone 0 Explosion- proof Intrinsic safety Pressurized Division Instrumentation Control Systems Area Electrical Classification Equipment, Installation, Maintenance Affecting: 25 Equipment Type Comparisons Electrical Code US Electrical Code Class, Division - Explosion proof 1.1 Scope. Many hoist manufacturers can furnish equipment to comply with the various classifications. The intrinsically safe rating means the electronics cannot spark or create sufficient energy to ignite. While only some of these materials are conductive, all are explosive. Certification is performed in close . In particular, employers should consider whether a fire could lead to an explosion, how fast a fire might grow, what other materials might be rapidly involved, any dangers from smoke and toxic gases given off, and whether Critical aspects: 1. NFPA 70, National Electrical Code, 20112017 edition. Explosion classified areas are defined by the following classes, divisions and groups, by the National Electric Code (NEC) (*See caution below). Explosion proof connector, NEC 500 Class 1, Div 2. Learn more. This design allows internal ignition sources, like sparks and (limited) hot spots. Approximately one fourth of these are caused by dust from food products or animal feed. Protection of Life. When an . Type 9: Dust-ignition proof.

Basic design is: enclosure is strong enough to withstand internal explosion. Indoor use in locations classified as Class I, Division 1, Groups A, B, C or D hazardous locations as defined in the National Electric Code (NFPA 70) (Commonly referred to as explosion-proof). 'Protective systems' means design units which are intended to halt incipient explosions immediately, and/or to limit the effective range of explosion flames and explosion pressures. . Two examples of this are the screw-on type junction box covers (Figure 1), and the tight tolerance, wide-machined flange between the body of the enclosure and its cover (Figure 2). . Multi-stream H.265 and H.264--ExSite Enhanced Fixed 2 Series Starting at $ Learn More- pdf | 0.38 MB. For permanent installations, such an installation may include "intrinsically safe barriers" that are located outside the hazardous location, and limit the amount of energy available to the device located in the hazardous area. First, the motor must be constructed in such a way that it will be able to completely contain an internal explosion without rupturing. Not as Common.
