Writer:admin    Released:2018-06-30 09:12:41    Type:【L】【M】【S
As we all know, the production of glass fiber reinforced plastic is, some of the raw material is harmful to human body, such as resin and some auxiliary materials contained many volatile toxic substances, in terms of labor protection, insufficient recognition of many enterprises at present, and does not need too much equipment for the production of hand lay-up, roughing and therefore easier to ignore.Because the FRP used in the raw materials, often with varying degrees of toxicity, so that the operator skin allergy, dizziness, white blood cells, chronic laryngitis, gastrointestinal discomfort.Volatile, some raw materials and stimulating, such as asbestos dust powder, glass fiber, Si02, styrene, toluene, acetone, and various acid anhydride, etc., some still flammable, and have an explosive mixture with air.Attention should be paid to the following points for reference:
(1)FRP producers are exposed to both glass fibers, harmful gases, and hazardous dust. Therefore, conditions need to be created to set up washrooms and showers.
(2) the environmental protection department is invited to inspect the harmful gas and dust in the workshop on an irregular basis, comparing it with the permitted concentration stipulated by the state, so as to have a good idea and solve the problem. As for the toxicity of chemical drugs, non-toxic, toxic size, generally according to the size of mice oral lethal dosage to distinguish.
(3) no diet and no smoking at the construction site.
(4) the workshop shall have a rest room, which shall be separated from the construction site.
(5) unified use of nutrition expenses, providing milk or other nutritious soup and vegetables for the workers, which is the real concern for the workers and the best use of the goods.
(6) don't wash your hands with acetone, toluene, or styrene.
(7) strive to choose low-toxic curing agent. Phenyldimethylamine, diethylenetriamine, polyamide no. 600 and mimidazole are the preferred low toxic curing agents in epoxy FRP.
(8) the construction personnel shall have regular physical examination, and if they are not really suitable for the work, they shall be transferred out in time.
(9) work clothes, work caps, aprons, masks, etc. shall be worn during construction.Wear protective glasses when polishing and dressing.If the curing agent enters the eye, wash the eyes thoroughly with 5% sodium ascorbate or 3% sodium bicarbonate (bicarbonate of soda) solution immediately, or rinse with water and go to the hospital.It is not suitable to wear wire gloves when machining or using curing agent because curing agent is easy to be immersed.Wear a dust mask and windshield if necessary, because dust with a diameter of less than 10 microns is harmful.
(10) construction of short sleeves, shorts and slippers shall be prohibited. The hands, especially the five fingers, should be coated with protective paste.You can also wear latex gloves.
(11) all FRP corners and wastes shall only be treated as garbage and shall not be burned, because the components of harmful gases produced by FRP combustion include: hydrocyanic acid, CO, hydrogen halide, C02, etc. Easy to cause public harm.
