- Malignant search for term
-
Malignant is a term applied to a tumor which is cancerous and capable of undergoing metastasis (invasion of surrounding tissue).
- Management commitment search for term
-
It is often said in occupational health and safety that management commitment is a pre-condition to success in occupational health and safety. Management commitment is shown by policy, leadership, and the dedication of resources.
- Management review search for term
-
A management review is a review by senior management of the effectiveness of the occupational health and safety management system. This is usually done through an audit of the management system.
- Manager search for term
-
A manager is a person higher up the organizational chart than a front-line supervisor. Occupational health and safety legislation may include managers within a definition of ‘supervisor’ or within a definition of ’employer.’ Accordingly, managers may have general duties for either supervisors or employers. Under a sun safety program, consideration should be given to the roles and responsibilities of managers, as distinct from others in the organization.
- Medical aid search for term
-
Medical aid is the assistance provided to an employee by a health care professional following an unwanted incident. A visit to a hospital emergency room would normally count as medical aid. It is more serious than most instances of ’first aid’ which usually occur at the workplace and which are often provided by fellow employees. The workers’ compensation regimes in each province and territory in Canada will usually have definitions for first aid and medical aid.
- Melanoma search for term
-
Melanoma is the most serious form of skin cancer. It can be fatal if untreated. Melanomas are cancers which arise from pigment cells in the skin. They are usually noticed in their early stages as being an unusual looking mole, or because they have changed color, shape or feel. Melanomas occur at all parts of the body, but often are seen on the back. They can grow and spread to other parts of the body quickly and so early detection and treatment is critical. Regular skin checks are important. People should regularly check skin spots for the ABCDE’s: are they Asymmetrical, with an irregular Boarder, having different Colors, an increasing Diameter or are they Evolving or changing in some way. Exposure to ultraviolet radiation, particularly from the sun and some artificial sources (e.g. tanning devices) is the main cause of melanoma. Also see skin cancer and non-melanoma skin cancer.
- Metastasis search for term
-
Metastasis is a process by which cancer cells spread throughout the body from their original source.
- Micron (µm) search for term
-
A micron is one millionth (10-6) of a meter. It is used when describing wavelengths. Also see nanometer.
- Minimal erythema dose (MED) search for term
-
Minimal erythema dose is the ultraviolet exposure that will produce a just-perceptible sunburn (erythema) 8 to 24 hours after someone has been exposed. Unfortunately, the MED is not a ‘standardized’ measure because it relates to a specific individual. Standard erythema dose is now often used instead of MED.
- Model Sun Safety Program search for term
-
Our Model Sun Safety Program is a program of an occupational health and safety management system that is focused on the effective prevention and management of health risks associated with sun exposure within the workplace. There are six steps to implementing the program: Core, Plan, Do-Control measures, Do-support, Check, and Act. Our program has been based on OHSAS 18001:1999 and CSA Z1000-14.
- Monthly safety summary search for term
-
Monthly safety summaries collate workplace safety data on a monthly basis. The data collected may include: the number of workers hired and trained, number of safety talks and attendance, number and outcomes of hazard/risk assessments (for example, sun safety risk assessments), number and details of first-aid treatments, number and details of incidents, and the number and outcomes of incident investigations. Analysis and review of these data help a workplace identify trends and issues for action.
