Safety Instructions in Handling Cutting
a. Areas near cutting tables should be clearly marked, and their access restricted should be restricted by barriers.
b. On motorised and automatic cutting tables the warning signals should be fitted to indicate when blade is in motion.
c. The machine ideally should be fitted with automatic adjustable guards to fully cover the exposed part of the cutting blade.
f. The five finger chain blades should be available to all the operator working on knife and should be worn on all times during cutting work.
g. There should be a regular check on the condition of the light, guard, and table fittings.
h. Only fully trained operatives should be allowed to work on knives.
i. The operators' standards should be checked against the published operating practice on a regular basis and should be corrected wherever a deviation is found.
j. There should be an effective cleaning system in operation that prevents build up of fluff, fly and off cuts, thus reducing fire, health & trip hazards?
