Service Delivery 4 Hazardous Materials and Marking Systems
Aim To make students aware of hazardous materials and the marking systems in use to identify them.
Learning Outcomes At the end of the session students will be able to: Understand the marking systems used for the transportation of hazardous materials Understand the marking systems for premises containing hazardous materials.
Introduction The range of substances which may face personnel is immense and can be found in many different forms, presenting a variety of hazards It is important therefore that personnel are able to understand and use any marking system present to identify and gain information on the substances involved.
Categories of hazard Solid Liquid Gas Vapour Crystals Fumes. Primarily the hazard will take the form of the substance itself which may be;
Categories of hazard Inhalation into the body Ingestion into the body Absorption through the skin into the body The chemical itself. The substance becomes a hazard through;
Identification of Substances United Kingdom Transport Hazardous Information System (UKTHIS) The system comprises of a warning panel with five sections; The Emergency Action Code (EAC) The Substance Identification NumberThe Hazard Warning Diamond Specialist Advice Telephone NumberCompany Name or Logo. U.K.T.H.I.S.
Emits flammable gas in contact with water Miscellaneous dangerous goods Liable to explosion.
Non-toxic non- flammable gas Spontaneously combustible substance Oxidising substance.
Toxic gas Infectious substance. Corrosive substance
Hazchem card ‘E’: Public safety hazard. 2 nd. letter: PPE & action 1 st. figure: Firefighting media
Road tanker black & white voluntary marking scheme Used to indicate a substance which is classed as ‘low hazard’, i.e. not falling within the Dangerous Substances Regs 1981 Not required by law entirely at the tanker, operators discretion.
Road tanker black & white voluntary marking scheme Although a substance may be classed as ‘low hazard’ its release into drains or water courses may be catastrophic on the local ecological balance The substance should therefore be contained until the full ecological effects are known.
International carriage of dangerous goods by road (ADR) Tank vehicles entering the UK from countries which are signatories to the European Agreement on the International Carriage of Dangerous Goods by Road (ADR) will be marked with an orange plate which will bear two code numbers and secondly the UN number.

The Dangerous Substances (Notification and Marking of Sites) Regulations 1990 Requires the operator of a site having a total quantity of 25 tonnes or more of a dangerous substance to display warning signs A sign will be displayed at the entrance to the site to warn of the presence of dangerous substances.
General sign used to indicate the presence of a harmful substance on site Used to indicate the presence of more than one type of hazard in the same storage area A dangerous substance not described by other signs.
Unidentifiable sources Materials washed up on the beach Illegal dumping Used, waste or scrap materials Spillages from unidentified vessels.
Health and safety If, due to distance, marking system cannot be read approach only on advice from a competent person Take all necessary precautions, approach from upwind, uphill etc, using full protective clothing.
Health and safety The information contained in the various marking systems specify initial actions only Assistance must always be sought from Brigade Control.
Health and safety Hazard warning diamonds may only specify primary hazards, be aware of potential secondary hazards and take necessary precautions.
Health and safety Personnel should be alert to the possibility of an incorrect marking system being displayed.
Confirmation Assessments will be based on this lesson and the corresponding study note Learning Outcomes Understand the marking systems used for the transportation of hazardous materials Understand the marking systems for premises containing hazardous materials.
