Personal Protective Equipment (PPE) Christian Rantzau Specialist Chemical Adviser University of Melbourne Scope of the course • Understand why PPE is needed – What hazards are in the working environment? – What parts of the body we need to protect? • Determine what PPE is needed – What basic PPE should I wear? – What items of specialised PPE might I need? • Ensure PPE is worn – How does it fit correctly? – What are the Dos and Don’ts? Why do we need protection? • A hazardous environment may have: – Airborne materials • Dusts, fumes, particulates – Biological materials • Bacteria, viruses, other microbes – Chemicals • Corrosives, toxics, irritants, hazardous substances etc.. – Light • Ultra Violet, Infra Red • What other hazards exist in our environment? Why do we need protection? These hazards can enter the body via 4 ways: Ingestion • Eating food that has come into contact with contaminants Absorption (skin & mucous membranes) • Liquids, fumes, vapours etc. being absorbed • Radiation (UV, IR, Ionising) Inhalation • Breathing in dusts, vapours, fumes etc. Injection • Needlestick, scalpel cuts etc. What is PPE? Personal Protective Equipment includes: • Eye Protection – Glasses, goggles, face shields, barriers • Gloves – latex, nitrile, thermal, Kevlar, rubber, PVC, vinyl • Safety Shoes – Safety boots (i.e. steel caps), closed shoes, rubber boots • Protective Clothing – Lab coats, aprons, hairnets, overalls • Respiratory Protection – Masks (P1 + P2), respirators, SCBA • Head Protection – Hard hats, helmets • Hearing Protection – Ear muffs (Peltors) , ear plugs What is PPE? Each part of the body has Personal Protective Equipment includes: its own requirements: • Eye Protection Eye, Face – Glasses, goggles, face shields, barriers • Gloves Hand – latex, nitrile, thermal, Kevlar, rubber, PVC, vinyl • Safety Shoes Feet – Safety boots (i.e. steel caps), closed shoes, rubber boots • Protective Clothing The body – Lab coats, aprons, hairnets, overalls (torso, arms, legs) • Respiratory Protection Lungs – Masks (P1 + P2), respirators, SCBA • Head Protection Head – Hard hats, helmets • Hearing Protection Ears – Ear muffs (Peltors) , ear plugs Anywhere else???? Priority for Protection What areas are most at risk? The list below is in order of areas that are most important to protect on our body: Priority 1: • Eyes, Lungs, Face, Hearing Priority 2: • Torso, Hands, Feet Priority 3: • Arms, Legs, Thermal core With each of these areas, there is specific equipment we should use. The key is to know what items work on what parts of the body, and what they are best designed to protect us from. Control Measures Use a less hazardous chemical Use Class II cab or fume hood SOPs training and review Glasses, coat, gloves, mask etc. National Institute for Occupational Safety and Health - From the CDC web site - http://www.cdc.gov/niosh/topics/hierarchy/ PPE is the last risk management option – why? PPE is the last option that should be considered when controlling risk. We humans are lazy and forgetful – PPE use requires us to remember to use it and to use the right/suitable equipment. • Using PPE usually means we are up close and personal to the risk. • It is considered to be a “passive” option • PPE is not always there or “switched on” • Its use requires us to take conscious action in order for it to work as a safety control. PPE is the last risk management option – why? Imagine working as this bomb technician – would you prefer to be wearing your PPE and directly working on the bomb, or using a robot from a safe distance away?
