Safety Regulations

Many regulations exist to protect people, our environment and corporate interests against the risk of explosion, fire and toxic exposure. Whether through general guidelines, industry regulation or industrial insurance company specification, our safety shields are recognised and a control measure to
(a) prevent spray-outs from leaking pipe joints and
(b) control the leak path.

Current Regulations:-
DSEAR-- Dangerous Substances & Explosive Atmospheres Regulations
COMAH -- Control Of Major Accident Hazards
EI15 Energy Industry Area Classification Code
SOLAS Safety of Life At Sea
REACH Registration, Evaluation, Authorisation & Registration of Chemicals
MARPOL Marine Pollution

DSEAR-- Dangerous Substances & Explosive Atmospheres Regulations
Enforced by the Health & Safety Executive, DSEAR puts duties on employers and the self-employed to protect people from risks to their safety from fires, explosions and similar events in the workplace, this includes members of the public who may be put at risk by work activity.

Employers must:-

COMAH -- Control Of Major Accident Hazards
To prevent and mitigate the effects of those major accidents involving dangerous substances, such as chlorine, liquefied petroleum gas, explosives and arsenic pentoxide which can cause serious damage/harm to people and/or the environment. The COMAH Regulations treat risks to the environment as seriously as those to people.

There are many Top Tier COMAH sites in the UK, ranging from chemical manufacturer, fuel storage, explosives site and even whisky distilleries. Safety shields and flange guards are typically employed within these sites as control measures.  

EI15 Energy Industry Area Classification Code
Model code of safe practice Part 15: The Area classification code for installations handling flammable fluids (EI 15, formerly referred to as IP 15) is a well-established, internationally accepted publication that provides methodologies for hazardous area classification around equipment storing or handling flammable fluids in the production, processing, distribution and retail sectors.

“flammable atmospheres may also be formed where flammable fluids handles below their flash points are released in the form of a mist or spray. Such materials, normally regarded as non-hazardous, should be treated as hazardous when they are pumped or under pressure and are capable of producing a mist or spray due to the possibility of a release from a small hole or flange leak. They should be regarded as a Category C fluid generating a hazardous are as appropriate.”

“Porous spray guards can be used around flanges and known potential leak points, causing the material to coalesce back to a liquid… rendering it non-hazardous.”

SOLAS Safety of Life At Sea

Ship engine room fire is a considerable concern with many incidents having occured as a direct result of pipe joint failure. Oil spray onto hot surfaces and oil mist formation cause fire which in itself, will have devestating effects, let alone resulting power loss. 

Unfortunately many incidents have occured over the years, with several high profile fires onboard cruise ships which are directly attributed to pipe joint failure. Our shields are designed to prevent the spray and mist formation, resulting in a safe drip with no pressure build up. Further, we have assisted many individual ships and whole fleets, offering full surveying, supply and installation of shields for standard and non-standard fittings such as flanges, valves, expansion bellows, hoses and couplings. Contact us for further details.

International treaty concerning the safety of merchant ships. Historically, a great number of ship fires have been caused by hot oil spray-outs within the engine room. For this reason, in 2003 the IMO included oil spray protection within the SOLAS regulations. Under these regulations:-

"Oil fuel lines shall be screened of otherwise suitably protected to avoid, as far as practicable, oil spray or leakages onto hot surfaces, into machinery air intakes, or other sources of ignition. The number of joints in such piping systems shall be kept to a minimum.“

In addition to oil spray, high pressure steam (HP steam) is another application for our shields, with many thousands having been supplied for ships.

REACH Registration, Evaluation, Authorisation & Registration of Chemicals
REACH is a new European Union regulation concerning the Registration, Evaluation, Authorisation and restriction of Chemicals. It came into force on 1st June 2007 and replaces a number of European Directives and Regulations with a single system.

REACH aims:-

MARPOL Marine Pollution
The MARPOL Convention is the main international convention covering prevention of pollution of the marine environment by ships from operational or accidental causes. It is a combination of two treaties adopted in 1973 and 1978 respectively and updated by amendments through the years.

OTHER Safety Considerations

A common problem associated with combustible, flammable or LPG pipelines, are long-bolt flangeless valves, or long-bolt sandwich wafer valves. Essentially, the bolts are extended and exposed. In the event of fire, the heat causes these bolts to expand and lengthen. This allows the gasket to leak and given the nature of the process, will create considerable jet fire or worse.

The solution is a shield, either made from steel or fire-retardant fabric (certified) which will cover and thus protect the valve and bolts from external fire. This application is a slight variation on our safety shields but the design is very similar. Please contact us for further information on this special application.
