themselves or their employers.
Biopsy forceps which have a spiral construction and other accessories which are
difficult to clean by hand should be ultrasonically cleaned and rinsed prior to
autoclaving or disinfection. Other accessories requiring disinfection, including the
cleaning brushes themselves, should be cleaned in detergent using a soft brush
Protection of Personnel
It is essential that endoscopy staff have the correct personal protective
equipment available at all times and are trained in its use (Table II). Each
endoscopy unit must have a policy for dealing with disinfectant spillage and all
staff must be trained in its implementation. There should always be sufficient
numbers of trained staff and items of equipment to allow enough time for
thorough cleaning and disinfection to take place. Training of staff in these
aspects of their work is vital.
Personnel Protection in Endoscopy
1. Wear disposable waterproof aprons. These should be discarded if soiled
2. Use nitrile gloves which are long enough to protect the forearms from
splashes. These should be changed regularly because they absorb
3. Goggles prevent conjunctival irritation and protect the wearer from
4. Disposable charcoal-impregnated face masks may reduce inhalation of
vapour from disinfectants, but experience with them is not yet widespread.
5. An HSE-approved vapour respirator should be available in case of spillage
or other emergencies. It should be stored away from disinfectants as the
charcoal adsorbs fumes and respirators should be regularly replaced.
All staff using or coming into contact with glutaraldehyde should be included in a
health screening programme which comprises:
-Pre-employment enquiry regarding asthma, skin and mucosal symptoms, such
as rhinitis and conjunctivitis, and lung function testing by spirometry.
-Annual lung function tests by spirometry.
-Annual completion of a health questionnaire.
-Immediate notification of skin rashes, chest and sinus problems.
-Records must be kept for 30 years.
It is recommended that this policy is extended to include other disinfectants used
in endoscopy because hazards associated with the alternatives are largely
unknown. In addition, although endoscopy is not a designated 'exposure prone
procedure' (personal communication, Chief Medical Officer) it is strongly advised
that all staff involved in endoscopic practice should be vaccinated against
hepatitis B. Other recommendations relating to risk of needle stick injury and
hazards relating to open cuts, abrasions and other skin lesions, reported by the
previous Working Party, remain unchanged.
