contact.  The affected person may suffer from itching, tingling or burning sensations.  There are other types of urticaria. This includes immune sensitised reaction and happens in people who have previously become sensitised to a causative agent (eg latex protein in rubber gloves). This type of reaction is also called ACD.  Acne is an inflammatory disorder of the sebaceous glands. The
skin eruptions from acne may be mild, involving exposed areas
of the body, or severe covering of all the body.
 Occupational acne includes oil acne, coal-tar acne, and
chloracne.
 Others types are related to cosmetics, heat/cold and
mechanical forces.
 The incidence of oil acne has declined in recent years because of decreased use of neat cutting oils. Better performing oils and improved health and safety standards in the workplace helped this decline further.
 The eruptions resulting from oil acne are called oil boils. When the exposure is prolonged, skin cancer, such as cancer of the scrotum, may develop.  Oil acne amongst oil workers is rare because there are fewer opportunities for prolonged contact with crude oil or the heavier oil fractions.  Chloracne results from exposure to certain halogenated
aromatic hydrocarbons (eg polychlorinated biphenyles (PCBc)).
 Individual lesions of chloracne consist primarily of blackheads,
whiteheads and cysts.
 Choracne occurs mainly on exposed areas of the skin, but
following regular exposure, lesions may appear in other regions
especially the genital, groin and axillae areas of the body.
 Chloracne usually begins several weeks or months after the
exposure and new lesions may appear even when exposure
stops, because there may still be traces of the contaminants in
the follicular areas of the skin.

 Coal-tar acne is associated with coal tar-based products and may
be aggravated by light/UV.
 Skin and eyes are vulnerable and it will cause increased
pigmentation as well as acne-related symptoms (eg skin
eruptions blackheads)
eruptions,
blackheads).
 Skin pigmentation disorders cause the skin to appear lighter or darker
than normal.
 Pigmentary disorders can be due to hazardous agents found in the
workplace (eg: UV, X-rays), environment (eg Sun rays) or ones

 Exposure to radiation can lead to skin cancer, most
commonly this comes from exposure to the sun. Therefore
outside workers are particularly at risk.
 People who are exposed ionising and non-ionising radiation
may be susceptible to work related cancers.
cancers
 Some chemicals can cause cancer on the skin, others may
contribute to cancers found in other parts of the body.
 The use of unrefined mineral oils has in the past led to skin
cancer affecting the exposed skin of the hands and
forearms.
 Oil-soaked clothing and oily rags kept in overalls caused
scrotal cancer.
 The use of refined oils together with changes in work
practice and improved personal hygiene have reduced this
risk.
 Chemicals like Mobca is used in the manufacture of
polyurethane products. It can get through the skin and may
cause cancer in other parts of the body.

Kontrol Teknik
Merencanakan proses industri yang sedapat mungkin
menghindari/mengurangi kontak langsung pekerja
dengan bahan-bahan yang digunakan.
Pendidikan
Para pekerja harus diberi informasi tentang bahanbahan yyangg berbahaya
y bagi
g kulit,, yyang
g sering
g
digunakan dan bagi mereka harus ditanamkan
pengertian untuk menghindari kontak langsung dengan
bahan-bahan tersebut.
Higiene Menjaga kebersihan tubuh merupakan salah satu
pencegahan terbaik untuk mengurangi kerusakan pada kulit
dan sebaliknya jika bekerja memakai pakaian kerja
 Klinik dan tempat perawatan
Deteksi dini: pemeriksaan periodik, lapor diri
Supervisi: perawatan oleh perawat
Pekerja yang mengalami kerusakan pada kulitnya harus segera dikirim ke klinik untuk mendapatkan pertolongan segera dikirim ke klinik untuk mendapatkan pertolongan, sehingga mencegah kerusakan yang lebih parah.
 Isolasi‐substitusi bahan/proses
 APD
Ada beberapa cara pencegahan yang dapat dilakukan,
yaitu:
• Kontrol teknik
• Pendidikan
• Tes penempatan kerja
• Klinik dan tempat perawatan
Alat perlindungan
Seperti: - sarung tangan karet
- penutup muka
- sepatu boot
- cream pelindung
- kaca mata
- sabun basa
Tujuannya untuk mengurangi kontak langsung antara bahan
dengan kulit.

 Flush area immediately with large quantities of fresh water, using an installed deluge shower or hose, if available. Avoid excessive water pressure. Continue to flush the area for at least 15 minutes while removing the clothes, including shoes, socks, and jewelry. Dry lime powder (alkali burns) creates a corrosive substance when mixed with water; keep the powder dry and remove it by brushing it from the skin. Acid burns caused by phenol (carbolic acid), should be washed with alcohol Then wash the area with large quantities of water washed with alcohol. Then wash the area with large quantities of water. If alcohol is not available, flush the area with large quantities of water. Cover chemical burns with a sterile dressing.  Material Safety Data Sheet (MSDS) for the chemical.  Flush the eyes with fresh water immediately using an installed emergency eye/face bath or hose on low pressure for at least 20 minutes. Ask casualty to remove contact lenses. Use your hands to keep the eyelids open. Never use a neutralizing agent, mineral oil, or other material in the eyes.  Monitor the airway, breathing, and circulation (ABCs).  Warning ‐ Do not attempt to neutralize any chemical unless you are sure what it is and what substance will effectively neutralize it. Further damage may be done by a neutralizing agent that is too strong or incorrect. Do not apply creams or other materials to chemical burns.  Treat for shock ‐ Keep the casualty comfortable and warm enough to maintain normal body temperature.  Request medical assistance for all chemical burns. If possible, before transport, notify medical personnel of the name and other pertinent information about the chemical involved, location of the burn, and percentage of the body area affected. Send the container to medical personnel with the casualty. 10

 For every task undertaken at your workplace, know what products or substances are being used or generated.  Find out what are the health and safety hazards associated with each of the substance or product used or generated. Find out whether these substances carry warnings signs and hazard information on dangers to the skin. You can find these on product labels and/or in Safety Data Sh
Sheets. SDS must be provided by the supplier of the chemical. SDS b id d b h li f h h i l  Frequent contact with water (wet working) is a major cause of WRD. Some substances (eg: formaldehyde in metal working fluids) may be generated during work and can cause WRD. Take account of wet work and substances generated during work in the next step.  Find out which of your employees are exposed to these substances, how does their skin come into contact, for how long and the frequency.  Find out what control measure you have in place.  Based on these make a judgement whether your employees are at risk of getting work related dermatitis.  If there is a risk of WRD, can you get rid of the chemical altogether? This is the best and simplest solution.  If you cannot get rid of the offending chemical, can you able to replace it with a less harmful chemical. Seek the advice of your Trade Association.  Introduce process controls so that skin does not come into contact with the chemical If the contact is by immersion or contact with the chemical. If the contact is by immersion, or splash find a solution that would provide a safe working distance (SWD) between the chemical and the skin.
 If the exposure is due to dust, vapour in the air, install a ventilated enclosure or provide local exhaust ventilation. Consult “COSHH Essentials”. It is likely to provide a suitable engineering control for your task.  If you have provided all the above controls and you consider that skin 

exposure could not be prevented altogether, then provide chemical protective gloves and coverall as appropriate. Selection of gloves is a complicated process. Always seek the help of your chemical supplier or a reputable PPE supplier. Make sure employees: have been taught on safe working practices; use the controls provided; have been trained to correctly use process equipment and PPE; know how to check their skin for signs of dermatitis; understand the benefits and limitations of skin care creams. Provide mild skin cleaning cream that will do the job and washing facilities with hot and cold water. Tell employees to clean their hands before consuming drinks and food or before wearing gloves. Ensure pre and post work creams are used. Seek the help of occupational health professionals if you suspect that you may have dermatitis problem at your workplace. Put in place a management system that checks that all of these actions are carried out in practice. You should take particular care if you have:
 fair or freckled skin that doesn’t tan, or goes red or burns before it tans;  red or fair hair and light coloured eyes;  a large number of moles. In the short term, even mild reddening of the skin from sun exposure is a sign of damage. Sunburn can blister the skin and make it peel.
Longer term problems can arise. Too much sun speeds up ageing of the skin, making it leathery, mottled and wrinkled. The most serious effect is an increased chance of developing skin cancer.

 Keep your top on.  Wear a hat with a brim or a flap that covers the ears and the back of the neck.  Stay in the shade whenever possible, during your breaks and especially at lunch time.  Use a high factor sunscreen of at least SPF15 on any exposed skin.  Drink plenty of water to avoid dehydration.  Check your skin regularly for any unusual moles or spots. See a doctor promptly if you find anything that is changing in shape, size or colour, itching or bleeding. SELAMAT UTS
