Many chemicals are used in the printing industry including inks, adhesives, lacquers and cleaning solvents. All of which can cause various levels of ill health if workers or employees are exposed to them.
Various vapours and mists can be inhaled and chemicals can cause skin problems or further damage to other body parts if absorbed into or just in contact with a person’s skin.
Process: Etching, Engraving, Platemaking, Photographic Reproduction
Risk: Nitric, sulphuric and hydrofluoric acids can cause skin burns, eye damage and blisters.
Process: Concentrated photographic developer or fixer solutions
Risk: Acidic salt solutions and Hydroquinone can irritate eyes and even cause dermatitis
Process: Adhesive laminating
Risk: Isocyanate prepolymers can cause an irritation of the airways and lungs leading to occupational asthma.
Process: UV and infra red curable inks, varnishes and lacquers
Risk: Reactive acrylates or methacrylate’s can cause corrosion of the skin, eyes and mucous membranes.
Process: UV lamps for photo processing, UV curing and high speed printing – ink misting
Risk: Fumes can cause irritation of respiratory tracts with the potential for occupational asthma as well as severe headaches and nausea.
Process: Lithographic platemaking, Gravure cylinder preparation and photoengraving.
Risk: Ammonium, potassium and sodium dichromate’s are all very corrosive and can cause deep ulcers as well as a risk of cancer.
Process: Lithographic fount solution, blanket restorers, cleaning solvents, Gravure and flexographic
Risk: Alcohol, Esters and Ketones can cause dermatitis, dizziness and other effects of the central nervous system.
Process: Flexographic, Dyeline Printing and Screen Inks
Risk: Perchloroethylene, Ammonium hydroxide and Ketones can cause dizziness, drowsiness and other effects on the central nervous system via inhalation.
Process: Screen Cleaning chemicals
Risk: Strong alkalis such as concentrated sodium or potassium hydroxide,
Oxidisers and sodium hypochlorite solvents can cause corrosion of the skin, eyes and mucous membrane as well as dizziness and drowsiness
Process: Digital (ink-jet) printing
Risk: Methyl ethyl ketone and propanol can cause abnormal heart rhythm and rate and can affect the liver and kidneys on long term exposure.
The law, called Control of Substances Hazardous to Health Regulations (COSHH), requires you to adequately Control Exposure to materials in the workplace that cause ill health by identifying which harmful substances may be present in the workplace, deciding how workers might be exposed to them and be harmed. Then to look at what measures are in place to prevent this harm and deciding whether you as a company are doing enough to prevent it.
You must then provide relevant information, instruction and training to your staff and in appropriate cases, provide Health Surveillance.
For more information please read the COSHH Essentials For Printers guidance from the Health and Safety Executive.
