2. General prevention measures:
• 1- Avoid Irrational use of drugs.
• 2- Avoid exposure to chemicals or
carcinogenic agents.
• 3- Avoid smoking.
• 4- Good hygiene measures.
• 5- Avoid any irritant substances.
3. Preventive measures for eye:
• Safe systems of work
• Machinery guards, interlocks
• Dust suppression
• Enforce use of appropriate eye protection:
goggles, glasses, masks
• Information, instruction, and training.
4. Preventive measures for ear:
1-Avoid Causal exposure (industries) to prevent
hearing loss:
• Quarrying and mining
• Food industry
• Agriculture
• Entertainment industry (pubs, clubs, discos)
• Armed forces and security services
• Construction industry
• Metal working
• Aviation.
2-Prevention of otitis externa requires meticulous
aural toilet.
6. Prevention measures for nose:
Preventing exposure control:
In the health care industry, exposure to staff is
minimized by:
• Wearing masks for close clinical contact
• Observing infection control procedures
• Wearing filtering respirators, gowns, and
goggles for aerosol-inducing procedures
(bronchoscopy, post-mortems, intubation, chest
physiotherapy, nebulization).
7. Other preventive measures for nose:
1- Immunization against H. Influenza infection and other
infection.
2- Avoid prolonged use of corticosteroid or decongestant drugs.
3- Avoid cigarette smoking.
For non-life threatening allergies (Rhinitis) the following are
recommended:
• Avoid contact with NRL gloves or products
• Avoid areas where there is a risk of inhalation of powder from
NRL gloves worn by others.
• Substitute to other glove materials where appropriate, e.g.
nitrile, PVC, or neoprene.
• If use of NRL gloves is necessary they should be single use
disposable gloves and be low-protein (<50μg/g) and powder-
free.
8. Preventive measures for mouth:
• 1- Good oral hygiene.
• 2- Treat underling condition.
• 3- Avoid smoking.
• 4- Avoid irrational use of drugs.
• 5- Avoid chewing Qate.
9. Preventive measures for skin:
Avoid Causal exposures often occur in combination
• Chemicals or biological agents:
• irritants (common examples include weak acids
and alkalis, soaps and detergents, oxidizing and
reducing agents, solvents)
• sensitizing agents
• Frequent hand washing (wet work)
• Gloves and other PPE
• Mechanical trauma
• Radiation and UV light.
10. Preventive measures for skin:
Advise the employer about primary prevention
• • Substitution of known sensitizing agents with
suitable alternatives
• • Engineering controls (e.g. enclose computerized
cutting operations to reduce contact between cutting
oils and the skin of operators)
• • Use of PPE (gloves). Some components of gloves
(typically carbamates and thiurams used as
preservatives and accelerants) can themselves
cause sensitization.
• • Education about the risks and good hand care
11. Good hand care: measures to risk of irritant dermatitis
• Ensure hands are not wet for >2h/day or >20 times each day.
For potent irritants these exposure limits
• Avoid wearing gloves for >4h/day
• Use tools that avoid wet-work or contact with irritants
• Wash hands in warm (not cold or hot) water and dry thoroughly
• Use protective gloves from the start of wet-work
• Minimize glove use—induces dermatitis by occluding skin
surface
• If protective gloves used for >10min wear cotton gloves
underneath
• Keep gloves intact and dry inside
• Avoid introducing irritants into the gloves
• Do not wear rings at work—they trap water and contaminants
• Use lipid-rich moisturizing creams at and after work.
