1.Background – Chemical Hazards & Risk EDMS No. ???Slide 4 of ## Hazard refers to the inherent properties of a chemical substance that make it capable of causing harm to a person or the environment. Exposure describes both the amount of, and the frequency with which, a chemical substance comes into contact with a person, group of people or the environment. Risk is the possibility of harm arising from a particular exposure to a chemical substance, under specific conditions.

2.Hazard Spotting (summary) EDMS No. ??? Emergency Safety Showers and eye washes Slide 12 of ## Location: visible, unobstructed access; Tested once per week? Safety Form displayed?; Water flows at proper angles to flush the eyes or body; temperature controlled…around 20 C; clear (not cloudy or coloured) drinking water quality; Controlled on an annual basis, organized by the HSE Unit.
2.Case Studies EDMS No. ??? PPE Slide 13 of ## Are people wearing PPE in your building?
2.Case Studies EDMS No. ??? PPE Slide 14 of ## Signs displayed? Stored in a dedicated cupboard, not with chemicals? Properly maintained? Alternative sizes available (S/M/L) Fit-Test performed? Course Code: STRPE03TB ½ day Training Course for wearers of RPE: Course Code: STRPE01IF Test takes 15 minutes: - Normal Breathing - Deep Breathing - Head Side to Side - Head Up and Down - Talking….
2.Case Studies EDMS No. ??? Safety Signs Slide 15 of ## Hazard warning signs should reflect the real hazard(s) present; Avoid proliferation of signs; SCEM No : WARNING NOTICES AND LABELS; Signs can be ‘custom-made’.
2.Case Studies EDMS No. ??? LEV (Local Exhaust Ventilation) Slide 16 of ## All such devices are controlled on an annual basis (downdraught tables, fume cupboards, walk-in booth, moveable capturing hood etc.) organized by the HSE Unit. If the device FAILS the test it must not be used as a control measure until remedial action is taken. What is LEV?
2.Case Studies EDMS No. ??? Chemical waste Slide 17 of ## Suitable or original containers; Container labelled with the name of the chemical and the appropriate hazard symbols; Not mixed with incompatible chemicals; Spill retention for liquids (SCEM No ); EDH Internal Transport Request to Building 262.
3.Emergencies EDMS No. ??? Chemical spill Slide 18 of ## Small chemical spill (that can be dealt with safely, without undue risk to personnel, environment…): Use of absorbant material for liquid spill; Indoors: ‘Snow’ ( ), multi-purpose liquid absorbant; Outdoors: ‘ABSORBANTE LOURDE CALCINEE’ ( ), hydrocarbons, oils; Sheet Material ( C). >; Must NOT be USED for the absorption of the following products : mercury, hydrofluoric acid, Breox oil.
3.Emergencies EDMS No. ??? Chemical spill Slide 19 of ## Medium-Large chemical spill Call the Fire Brigade; Cordon/Safety perimeter established; Suitably Equipped Personnel (ppe, equipment...); Larger quantities of absorbant material; Special absorbant kits (e.g. for mercury); Decontamination of personnel; Environmental Protection; Transport of chemical waste to building 262.
3.Emergencies EDMS No. ??? Flammable Gas leak Slide 20 of ## Actions on Flammable gas detection: Level 3 Alarm to the Fire Brigade; Flashing warning panel; Siren; Close electro valves; Other actions? (e.g. Doubling of ventilation exhaust speed). 2 day Training Course for workers in ATEX areas: Course Code: STATH02IF
4.Analysis of Chemical Accidents EDMS No. ???Slide 21 of ## Each year approximately 6 accidents involving chemicals coming into contact with eyes; Generally low hazard chemicals, chemical irritants; Always wear suitable eye and/or face protection when handling chemicals (SCEM No ): Safety glasses: Minimum protection Safety goggles: corrosive liquids, dusts etc. Safety glasses over prescription glasses Visor (to be worn over safety goggles): high pressure, large quantities of corrosive liquids
