- The training program includes a pre-learning phase that allows participants to familiarize themselves with foundational concepts before engaging in in-person interactions with the facilitator.
- Following the pre-learning phase, participants will have the opportunity to meet with the facilitator in a physical classroom setting. This direct interaction is crucial for addressing any questions or concerns that may have arisen during the self-study period.
- Additionally, the physical classroom component is designed to facilitate hands-on practical training. This aspect of the program allows participants to apply theoretical knowledge in real-world scenarios, enhancing their understanding and retention of the material. Working under the guidance of an experienced facilitator, learners can practice skills, collaborate with peers, and gain valuable insights that are difficult to achieve through online learning alone.
- Overall, this structured approach—combining pre-learning with direct facilitator contact and practical classroom experiences—ensures a comprehensive and effective learning journey that accommodates various learning styles and maximizes participant engagement.

| Term | Definition |
| Approved Illumination Inspection Authority | A DEL approved provider for the monitoring of lighting in the workplace. |
| Aliasing | Aliasing occurs when you sample a signal (anything which repeats a cycle over time) too slowly (at a frequency comparable to or smaller than the signal being measured) and obtain an incorrect frequency and/or amplitude as a result. |
| Hazard | A hazard is any source of potential damage, harm, or adverse health effects on someone. |
| Health Risk Assessment | A health risk assessment is an instrument used to collect health information, typically coupled with a process that includes biometric testing to assess an individual's health status, risks, and habits. A Health Risk Assessment is an important part of the occupational health and safety (OSH) management plan. Through a HRA assessment, hazards and risks will be identified, who might be at risk, and where control measures are needed to prevent illness and injury. The main purpose of a health risk assessment is to focus on providing workers with a safe, healthy environment, improving safety and to reduce the potential liability issues faced a company. This process includes a thorough inspection of the work environment, equipment, and systems to determine potential hazards and implement safety systems to prevent injury. |
| Hierarchy of Control | The hierarchy of control is a system for controlling risks in the workplace. It is a step-by-step approach to eliminating or reducing risks and it ranks risk controls from the highest level of protection and reliability through to the lowest and least reliable protection. |
| Homogeneous Exposure Group | A group of workers engaged in similar tasks for the same period, in similar work shifts, in the same workplace and exposed to the same risk agent. In order to manage risks identified in a HRA or hygiene survey, the workers are included in a group called Homogenous Exposure Group (HEG). |
| Mitigation | Reducing risk of loss from the occurrence of any undesirable event. In general, mitigation is the action of reducing the severity, seriousness, or painfulness of something. |
| Occupational | Is work related or relates to the working environment. |
| Occupational Exposure Limit | An occupational exposure limit is an upper limit on the acceptable concentration of a hazardous substance in workplace to which a worker can be exposed over a period of time without suffering any harmful consequences. |
| Occupational Hygiene | The discipline of anticipating, recognising, evaluating, and controlling health hazards in the working environment with the objective of protecting worker health and well-being and safeguarding the community at large. |
| Occupational Hygiene Survey | A careful examination of the hazards in the workplace that can cause harm to people. It allows you to weigh up risks and to determine whether enough precautions are in place to avoid harm to your employees26. It anticipates, identifies, and quantifies hazards in the workplace in order to formulate controls that match the severity of the exposure and risk. The main purpose of an occupational hygiene survey is to communicate measures for the control of an exposure/s that could cause harm or adversely affect health, to provide legitimacy to the control measures recommended, be based on scientific evidence to support the conclusion that a health risk is of sufficient severity to warrant the extent/magnitude of controls recommended. |
| Occupational Hygienist | Occupational hygienists assess health risks in a workplace; sample air to determine if there are harmful substances present; measure noise levels in factories; supervise the safe removal from asbestos from buildings; and provide practical advice on how workers can be protected from job-related health and safety risk.26 |
| Risk | Risk is the chance or probability that a person will be harmed or experience an adverse health effect if exposed to a hazard. |
| Stroboscopic Effect | This is a visual phenomenon caused by aliasing (see definition above) that occurs when continuous rotational or other cyclic motion is represented by a series of short or instantaneous samples (as opposed to a continuous view) at a sampling rate close to the period of the motion. |
| Vision Conservation Programme | Can be defined as a programme aimed at the prevention of visual impairment and injury, involving the implementation of the following measures |
