61 BRIDON Oil and Gas Steel Rope Technical Information The worker should: 1) use oil impermeable gloves, or if not available, suitable oil repellent type barrier creams, 2) avoid unnecessary contact with oil using protective clothing, 3) obtain first aid treatment for any injury, however slight, 4) wash hands thoroughly before meals, before using the toilet and after work, 5) use conditioning creams after washing, where provided. The worker should not: 1) put oily rags or tools into pockets, especially trousers, 2) use dirty or spoiled rags for wiping oil from the skin, 3) wear oil soaked clothing, 4) use solvents such as parafin, petrol etc., to remove oil from the skin. Concentrations of oil mists, fumes and vapours in the working atmosphere must be kept as low as is reasonably practicable. Levels quoted in the current edition of HSE Guidance Note EH40 ‘Occupational Exposure Limits’ must not be exceeded. Health Hazards Inhalation of oil mists or fumes from heated rope lubricants in high concentrations may result in dizziness, headache, respiratory irritation or unconsciousness. Eye contact may produce mild transient irritation to some users. Fumes from heated rope lubricants in high concentrations may cause eye irritation. If heated rope lubricants contacts skin, severe burns may result. Prolonged or repeated skin contact may cause irritation, dermatitis or more serious skin disorders. Fibre Cores Being in the centre of a steel wire rope, the materials (natural or synthetic) from which fibre cores are produced do not present a health hazard during normal rope handling. Even when the outer core strands are removed (for example when the rope is required to be socketed) the core materials present virtually no hazard to the users, except, maybe, in the case of a used rope where, in the absence of any service dressing or as a result of heavy working causing internal abrasive wear of the core, the core may have decomposed into a fibre dust which might be inhaled, although this is considered extremely unlikely. The principal area of hazard is through the inhalation of fumes generated by heat , for example when the rope is being cut by a disc cutter. Manufacturing Rope Lubricants The products used in the manufacture of steel wire ropes for lubrication and protection present minimal hazard to the user in the as-supplied condition. The user must, however, take reasonable care to minimise skin and eye contact and also avoid breathing their vapours and mists. A wide range of compounds is used as lubricants in the manufacture of steel wire rope. These products, in the main, consist of mixtures of oils, waxes, bitumens, resins, gelling agents and fillers with minor concentrations of corrosion inhibitors, oxidation stabilizers and tackiness additives. Most of them are solid at ambient temperatures and provided skin contact with the fluid types is avoided, none present a hazard in normal rope usage. However, to assist in the assessment of the hazard caused by these products, the following table contains all the components which may be incorporated into a wire rope lubricant and which may be considered hazardous to health. Hazardous Ingredients: There are no other known constituents of any wire rope lubricant used that are classified as hazardous in the current edition of EH40. General advice on handling ropes with lubricants To avoid the possibility of skin disorders, repeated or prolonged contact with mineral or synthetic hydrocarbons must be avoided and it is essential that all persons who come into contact with such products maintain high standards of personal hygiene.
