A liquid with high surface wetting characteristics is applied to the surface of the part and allowed time to seep into surface breaking defects. The excess liquid is removed from the surface of the part. A developer (powder) is applied to pull the trapped penetrant out the defect and spread it on the surface where it can be seen. Visual inspection is the final step in the process. The penetrant used is often loaded with a fluorescent dye and the inspection is done under UV light to increase test sensitivity.
Most basic and common inspection method. Tools include fiberscopes, borescopes, magnifying glasses and mirrors. Portable video inspection unit with zoom allows inspection of large tanks and vessels, railroad tank cars, sewer lines. Robotic crawlers permit observation in hazardous or tight areas, such as air ducts, reactors, pipelines.
If the competent person finds a defect with the lifting equipment during the thorough examination and/or inspection which in their opinion is, or could become, a danger to people, they must tell you immediately and confirm this in the report of thorough examination/inspection. ■ If the competent person discovers a defect that involves an existing or imminent risk of serious personal injury , then they must tell you immediately and send a copy of the report to the relevant enforcing authority (HSE or the local authority), even if the defects are remedied immediately. A competent person who fails to report […]
An examination scheme involves a thorough examination and would include a detailed schedule of checks, appropriate examination techniques and testing requirements, drawn up to suit the operating conditions of a specific item of lifting equipment. This can help ensure that the resources you spend more accurately reflect the level of risk. The examination scheme: ■ should identify the parts of the lifting equipment to be thoroughly examined; ■ can cover a number of similar items subject to the same operating conditions, eg all the lifting accessories in a factory which are sufficiently similar in age and subjected to similar amounts […]
You must have lifting equipment thoroughly examined: ■ before using it for the first time – unless the equipment has an EC Declaration of Conformity less than one year old and was not assembled on site. If it was assembled on site, it must be examined by a competent person to establish the assembly was correct and safe, eg a platform lift installed in a building; ■ after assembly and before use at each location for equipment that requires assembly or installation before use, eg tower cranes; ■ regularly in service if the equipment is exposed to conditions causing deterioration […]
A competent person: ■ should have enough appropriate practical and theoretical knowledge and experience of the lifting equipment so that they can detect defects or weaknesses, and assess how important they are in relation to the safety and continued use of the equipment; ■ should not be the same person who performs routine maintenance as they would be responsible for assessing their own work; ■ should be sufficiently independent and impartial to make objective decisions; ■ may be employed by a separate company, or selected by an employer from members of their own staff.
A thorough examination is a systematic and detailed examination of the lifting equipment by a competent person to detect any defects that are, or might become, dangerous. The competent person will determine the scope of the thorough examination and they may use a number of sources to help them do this, such as industry guidance. HSE’s Contract Research Report Thorough examination and inspection of particular items of lifting equipment (CRR429) may also be a useful reference tool (see ‘Find out more’).
Some equipment used in lifting is not covered by LOLER. Where this is the case, you would still have duties under PUWER to ensure the work equipment is safe and suitable, for example: ■ equipment whose principal function is not lifting, for example conveyor belts or the three-point linkage on a tractor; ■ items such as pallets, skips, ladles, one-trip slings attached to a load and similar containers, which are considered part of the load. For lifting equipment used mainly by members of the public (such as lifts in shopping centres or train stations), you do not have duties under […]
LOLER addresses the specific risks associated with the use of lifting equipment. Thorough examination and inspection are key requirements of the Regulations. To meet these requirements, duty holders must: ■ ensure lifting equipment (including lifting accessories) exposed to conditions causing deterioration which could lead to dangerous situations undergoes regular thorough examination by a competent person; and ■ ensure all supplementary inspections and tests recommended by the competent person are carried out within the timescale stated. Examples of conditions causing deterioration are wet, abrasive or corrosive environments.
If you are an employer or self-employed person providing lifting equipment for use at work, or if you have control of the use of lifting equipment, you must make sure the lifting equipment is safe. The main requirements for you as a ‘duty holder’ are in the Provision and Use of Work Equipment Regulations 1998 (PUWER) and the Lifting Operations and Lifting Equipment Regulations 1998 (LOLER). This leaflet provides advice on the options you have under LOLER relating to the requirement for thorough examination and inspection of lifting equipment and explains the benefits of having an ‘examination scheme’. However, this […]
