A variety of materials are used in dental laboratoriesfor manufacturing crowns and bridges, chromium-cobalt
frameworks, acrylic dentures, and other dental products. The use of these materials has caused respiratory
diseases, dermatological problems and neurotoxicity between dental technicians. Adequate and efficient
protection should be considered to prevent occupationally related diseases. This study was conducted in some
cites at different parts of Libya to know how are the dental technicians awareness about laboratory safety. This
study was included of eighty seven technicians that are working in public and private dental laboratories (11 and
26 laboratories respectively) in the following cities; Tripoli, Benghazi, Sabha, Misurata, Zliten, Alkhoms, Alzawia,
Alejelat, Agdabia, Al-Bida, and El-Gubba. The questions were about type of laboratory, cleanness, working area,
crowded, quality of air freshen, lighting, suction of dust, protection of gas tubes and electric cable, present of lab
safety tools and uses of personal protection tools. The results showed that whose agree with the cleanness were
83.9% where 16.1% disagree, while the opinion of technicians whose agree with working area, crowded, quality of
air freshen, lighting, protection of gas tubes and electric cable were 82.8, 42.5%, 69%, 72.4%, 89.7% and 79.3%
respectively. While the percentage of disagree were 17.2%,57.5%, 31%, 27.6%, 10.3% and 20.7% respectively. The
laboratories safety tools (air suction, fire extinguisher, first aid box and emergency phone number) were present
in the laboratories in percentage of 51.4%, 32.4 %, 37.8% and 27% respectively. While correspondingly not present
in the percentage of 48.6%, 67.6%, 62.2% and 73%. Whereas the technicians used personal protection tools
(Eyeglasses, rubber gloves, thermal isolated gloves, lab coat, face mask and earplug) their percentages were 55.2%,
63.2%, 24.1%, 86.2%, 83.9 and 6.9%). While whose not used the personal tools their percentage were 44.8%, 36.8,
75.9% 13.8% 16.1% and 93.1 respectively. It can be seen that, the technicians were awareness about personal
safety, however they were less care about laboratories safety tools which are very important for their health and
safety. The study strongly recommends the dental technicians to follow the safety rule in their dental laboratories
