Guide to the PPE (Personal Protective Equipment)
What is PPE?
PPE is defined in the Regulations as ‘all equipment (including clothing affording protection against the weather) which is intended to be worn or held by a person at work and which protects him against one or more risks to his health or safety’, eg safety helmets, gloves, eye protection, high-visibility clothing, safety footwear and safety harnesses.
Hearing protection and respiratory protective equipment provided for most work situations are not covered by these Regulations because other regulations apply to them. However, these items need to be compatible with any other PPE provided.
Cycle helmets or crash helmets worn by employees on the roads are not covered by the Regulations. Motorcycle helmets are legally required for motorcyclists under road traffic legislation.
What do the Regulations require?
The main requirement of the PPE at Work Regulations 1992 is that personal protective equipment is to be supplied and used at work wherever there are risks to health and safety that cannot be adequately controlled in other ways.
The Regulations also require that PPE:
- is properly assessed before use to ensure it is suitable;
- is maintained and stored properly;
- is provided with instructions on how to use it safely; and
- is used correctly by employees.
Can I charge for providing PPE?
An employer cannot ask for money from an employee for PPE, whether it is returnable or not. This includes agency workers if they are legally regarded as your employees. If employment has been terminated and the employee keeps the PPE without the employer’s permission, then, as long as it has been made clear in the contract of employment, the employer may be able to deduct the cost of the replacement from any wages owed.
Health and Safety
Executive
Assessing suitable PPE
To allow the right type of PPE to be chosen, carefully consider the different hazards in the workplace. This will enable you to assess which types of PPE are suitable to protect against the hazard and for the job to be done.
Ask your supplier for advice on the different types of PPE available and how suitable they are for different tasks. It may be necessary in a few particularly difficult cases to obtain advice from specialist sources and from the PPE manufacturer. Another useful source of information is the British Safety Industry Federation
(www.bsif.co.uk).
Consider the following when assessing whether PPE is suitable:
- Is it appropriate for the risks involved and the conditions at the place where exposure to the risk may occur? For example, eye protection designed for providing protection against agricultural pesticides will not offer adequate face protection for someone using an angle grinder to cut steel or stone.
- Does it prevent or adequately control the risks involved without increasing the overall level of risk?
- Can it be adjusted to fit the wearer correctly?
- Has the state of health of those who will be wearing it been taken into account?
- What are the needs of the job and the demands it places on the wearer? For example, the length of time the PPE needs to be worn, the physical effort required to do the job and the requirements for visibility and communication.
- If more than one item of PPE is being worn, are they compatible? For example, does a particular type of respirator make it difficult to get eye protection to fit properly?
The hazards and types of PPE
Eyes
Hazards: chemical or metal splash, dust, projectiles, gas and vapour, radiation.
Options: safety spectacles, goggles, faceshields, visors.
Head
Hazards: impact from falling or flying objects, risk of head bumping, hair entanglement.
Options: a range of helmets and bump caps.
Breathing
Hazards: dust, vapour, gas, oxygen-deficient atmospheres.
Options: disposable filtering facepiece or respirator, half- or full-face respirators, air-fed helmets, breathing apparatus.
Protecting the body
Hazards: temperature extremes, adverse weather, chemical or metal splash, spray from pressure leaks or spray guns, impact or penetration, contaminated dust, excessive wear or entanglement of own clothing.
Options: conventional or disposable overalls, boiler suits, specialist protective clothing, eg chain-mail aprons, high-visibility clothing.
Hands and arms
Hazards: abrasion, temperature extremes, cuts and punctures, impact, chemicals, electric shock, skin infection, disease or contamination.
Options: gloves, gauntlets, mitts, wristcuffs, armlets.
Feet and legs
Hazards: wet, electrostatic build-up, slipping, cuts and punctures, falling objects, metal and chemical splash, abrasion.
Options: safety boots and shoes with protective toe caps and penetration-resistant mid-sole, gaiters, leggings, spats.
Training
- Make sure anyone using PPE is aware of why it is needed, when it is to be used, repaired or replaced and its limitations.
- Train and instruct people how to use it properly and make sure they are doing this.
- Because PPE is the last resort after other methods of protection have been considered, it is important that users wear it all the time they are exposed to the risk. Never allow exemptions for those jobs which take ‘just a few minutes’.
- Check regularly that PPE is being used and investigate fully any reasons why it is not. Safety signs can be useful reminders to wear PPE.
Maintenance
Make sure equipment is:
- well looked after and properly stored when it is not being used, for example in a dry, clean cupboard, or in the case of smaller items, such as eye protection, in a box or case;
- kept clean and in good repair - follow the manufacturer’s maintenance schedule (including recommended replacement periods and shelf lives). Simple maintenance can be carried out by the trained wearer, but more intricate repairs should only be done by specialists.
Make sure suitable replacement PPE is always readily available.
CE marking (for
Ensure any PPE you buy is ‘CE’ marked and complies with the requirements of the Personal Protective Equipment Regulations 2002. The CE marking signifies that the
PPE satisfies certain basic safety requirements and in some cases will have been tested and certified by an independent body.
Key points to remember
Are there ways (other than PPE) in which the risk can be adequately controlled, eg engineering controls? If not, check that:
- PPE is provided;
- it offers adequate protection for its intended use;
- those using it are adequately trained in its safe use;
- it is properly maintained and any defects are reported;
- it is returned to its proper storage after use.

Six element of Ergonomics program
6 Langkah dalam melaksanakan Program Ergonomi ditempat Kerja adalah
- Management Commitment
Management sebagai pengambil keputusan harus memiliki komitmen dalam mendukung terlaksananya program Ergonomi dengan menyediakan segala kebutuhan dalam menerapkan program tersebut. Anda juga harus dapat menyakinkan ke managemen tentang betapa pentingnya program ini dilakukan.
Contoh: Kebijakan Perusahaan; Membuat Prosedur; Membuat proposal tentang program ergonomi.
- Hazard Information & Reporting
Anda harus membuat system yang mempermudah pekerja dalam pelaporkan adanya tanda atau gejala MSD, ini berguna untuk melakukan respon yang tepat dan cepat.
Contoh: Pengembangan sistem database antara Medical Operator (RS/Clinic Perusahaan dengan SHE personal (Industrial Hygiene). Beberapa software yang bisa dipergunakan adalah Microsoft Access; Medgate; Ellipse; dsb
- Assessment
Setelah informasi mengenai MSD didapat/dilaporkan maka selanjutnya dilakukan analisa mengenai permasalahan tersebut untuk mengetahui faktor resiko ergonomi yang dapat menimbulkan terjadinya MSD. Ini bisa dilakukan dengan membuat hierarki control
Contoh: dengan melakukan JHA (Job Hazard Analysis)
Form JHA
Langkah Kerja | Kemungkinan Bahaya / Deskripsi Event | Tingkat Resiko | Antisipasi / Tindakan Perbaikan |
- Education
Selain kita membuat materi training secara general (sesuai dengan bahaya umum di suatu lokasi kerja/perusahaan) diperlukan juga “Area Specific Hazard Training” maksudnya dengan memberikan materi yang lebih detail kepada pekerja. (misalnya yang di area kerjanya memiliki resiko terjadinya MSD dilakukan training ergonomic)
Contoh: Annual refresher training untuk semua pekerja, Spesific hazard Training untuk pekerja diarea tertentu, dsb
- MSD Management
Anda harus merespon segera terhadap kondisi pekerja yang beresiko MSD untuk mencegah kondisi mereka semakin buruk. Berikan mereka akses yang mudah ke “health care professional” untuk melakukan konsultasi dan mendapatkan rekomendasi yang tepat.
Contoh: Adanya dokter perusahan (Occupational Health Doctor), harus dipastikan bahwa dokter yang bersangkutan sudah berpengalaman dalam permasalahan kesehatan di lingkungan kerja, permasalahan ini pernah dialami penulis ketika dokter OH-nya sangat kesulitan memberikan rekomendasi karena kurangnya informasi tentang kesehatan kerja.
- Program Evaluation.
Perlunya dilakukan evaluasi secara periodik terhadap program ergonomik paling sedikit 3 tahun sekali. Ini berguna untuk menyakinkan bahwa program yang telah dibuat sesuai dengan kebutuhan perkembangan perusahaan.
Contoh: Review Prosedur secara berkala
*MSD =Musculoskeletal Disorder
