EXPLOSION PROTECTION

11.1 EARTHING

 

The hoist or hoist and trolley should normally earth through the top hook or the running wheels of the trolley into the supporting steel structure. If

 

this does not happen then the hoist can earth through the load chain of the hoist, when grounded. If the chain is rusty it can affect the earthing   

 

of the hoist. During inspection the chain may need cleaning, oiling or replaced to allow adequate earth leakage. If the earth leakage is less than

 

that recommended a separate earth strap should be fitted. Neither the running surface of beams nor the wheels should be painted. During lifts the  

 

load may be required to be earthed if there is any doubt as to the earth leakage from the hoist.  

 

IMPACT HAZARDS

 

The materials chosen and their coverings should help to prevent an ignition hazard so that a corroded section of steel does not impact against a  

 

light metal or high grade steel. The selected materials and the design should exclude as far as possible mechanical sparks due to impact, sliding  

 

or friction. Where external housings are made of aluminium then the possibility of impact should not be possible.

 

PLASTIC SURFACES

 

Where plastic has been used for the pendant, control boxes or on the hoist these surfaces must only be cleaned with a damp cloth (water), which  

 

reduces electrostatic charging due to friction from wiping with a cloth.

 

COMPRESSED AIR HOSES

 

All air hoses used in a Zone 1 + 21 & 2 + 22 areas should be ‘Anti-Static’ with a sufficiently low surface resistance to prevent an electrostatic  

 

ignition hazard. The Hose should always have a higher Safe Working Pressure that the hoist and above that of the air supply from the  

 

 compressor.

 

 

Air supply hoses need to be certified with a current report on the condition of the hose and checked before fitting to the hoist. The burst of a hose  

 

or connection failure can create a dust cloud and also create a static charge.

 

 

Hose safety whip cables should be used to prevent hoses flying if a connection fails to limit the dust cloud and the flying hose.

 

*Red Rooster hoists should only be operated with compressed air.

 

MINING APPLICATIONS

 

In general most standard Red Rooster hoists can be used for underground mining operations along with the surface buildings and services. The 

 

equipment is certified for Group I M2 use, so must be switched off / isolated in the event of an emergency. The equipment has to be robust, non- 

 

sparking, taking into account the conditions and the handling underground and be built to survive along with explosive protection from Methane  

 

gas / dust - Firedamp. The maximum surface temperature of 150°C for coal dust atmospheres will not be reached where a coal dust layer can be  

 

formed or 450°C where coal dust will not form a layer.

 

For mining hoists the lubrication oil shall be replaced with non-flammable substances or substances not capable of forming explosive  

 

 

atmospheres (BS EN 1127-2:2014). Hoist lubrication is controlled by the drip setting on the lubricator and set as per the manual.

 

▪ 

During use the operator must avoid loads or the bottom hook impacting with surrounding steel equipment and structural steel  

 

 

                     which may result in sparking or frictional sparks caused by dragging loads past fixed structures. 

 

▪ 

Any impacts involving light metal or cast iron should be avoided and these materials either protected or removed from the area. 

 

▪ 

Damaged or badly corroded coatings or chain should be replaced or repaired to keep up the UK Ex / ATEX rating of the  

 

 

 

equipment. For assistance contact RRL. 

 

▪ 

Earthing of hoists is not usually required as the hook connection to structure allows the hoist to connect to earth.  

 

 

 

 

▪ 

The running surfaces of beams and cranes should not be painted to allow wheels to earth to the structure. 

 

▪ 

Stainless steel ‘C’ track systems should be applied with an earth wire to connect onto the structure. 

 

▪ 

Plastic junction boxes should only be cleaned with water and a clean cloth to reduce any electrostatic charge coming from the    

 

                     rubbing of the plastic surface. 

 

▪ 

Dust should not be allowed to accumulate on the hoist, trolley, crane or junction boxes. 

 

▪ 

Only use a damp cloth for wiping plastic surfaces.
