Chemical Permeation through Disposable Gloves
Published in Robert N. Phalen, Howard I. Maibach, Protective Gloves for Occupational Use, 2023
It is crucial to be aware that the permeation of some highly toxic chemicals through disposable gloves can be efficient and rapid. One provided example on the subject is tragic. Dr Karen Wetterhahn, a toxicologist, died in 1997 of mercury poisoning after 15 months had passed from a work task in which she transferred a small amount of dimethyl mercury to a nuclear magnetic resonance (NMR) tube while wearing disposable NR gloves.101 Effective chemical protective gloves existed at the time and could have saved her life. Another example of hazardous materials includes polychlorinated biphenyls and their solutions and the use of surgical NR gloves that have been rated as providing poor protection.102
What Promotes Joy

The four broad categories of emergency management are mitigation—preventing something or lessening the blow. A good example is a hurricane coming. You can’t stop that, but you can do things to lessen the impact and help people. Then there is preparedness—being prepared for whatever emergencies arise. An emergency manager has to make sure people are prepared with plans, equipment, and other things to handle whatever their town or city faces, whether it’s flooding or a hurricane or other weather events. And, of course, now in the world we live in, everybody has to be ready to deal with a terrorist attack or an active shooter. Emergency managers have to make sure they have a response for all these situations—that they have fire, EMS, a hazardous materials (HAZMAT) team, things like that. Another big category is recovery. How do you recover from whatever happened? The fire, police, and EMS are all part of an emergency management plan. That work for the university has carried over into my current job.
Education and Training in Radiation Protection

In addition, the Occupational Safety and Health Administration (OSHA) has developed a series of detailed training requirements that also are applicable to workers exposed to radiation and/or other hazardous materials.39 Several new regulations involving radioactive and other hazardous materials must be followed to develop and conduct training programs that comply with the Resource Conservation and Recovery Act (RCRA), the Superfund Amendments and Reauthorization Act (SARA), the Hazard Communication Standard (HAZ-COM), substance-specific regulations, and Department of Transportation (DOT) regulations. Training regulations apply to facilities that are involved in the generation, storage, treatment, transportation, or disposal/removal of hazardous materials/waste. Moreland et al.40 have summarized a training program for compliance with SARA training of hazardous waste workers (OSHA regulations 29CFR 1910.120), HAZCOM training for all personnel working with hazardous materials (OSHA regulation 29CFR 1910.1200), RCRA training in hazardous waste management and emergency plans (EPA regulation 40CFR Part 265.16), and DOT training for workers involved in any transportation activities under 10CFR 49 (DOT regulations 49CFR Part 173). The workers covered by RCRA are approximately the same as those requiring OSHA (SARA) training under 29CFR Part 1910.120.

Controlling the spread of Mpox depends on contact tracing. Interviewing Mpox patients will help identify contacts for contact tracing. Face-to-face contact, direct physical contact (including sexual contact), and interaction with infected objects such as beds or other items with shared usage are examples of contact mediums [5]. Anyone who has interacted with the patient in a hospital environment should be identified. A person who has been exposed to someone with Mpox should be watched for symptoms such as fever, chills, rash, and lymphadenopathy for 21 days following the last exposure, and if necessary, administered a vaccine as PEP [5]. People who have Mpox should be separated from family members, pets, and other people in a private room in the emergency room, a hospital room, or another private place. Additionally, while they are contagious, they should avoid close contact with others. Until all lesions have healed and a fresh layer of skin has grown below, isolation should be maintained. Mpox waste is categorized as a Category A material (a pathogen that is life-threatening or causes permanent disability). Therefore, it is necessary to handle and manage clinical waste in line with the US Department of Transportation Hazardous Materials Regulations [5]. The greatest worry for human-to-animal transfer concerning pets is with pet rats. Transmission to other animals, such as dogs and cats, is a possibility but is not well-defined and has to be further assessed. The current advice is to quarantine pet rats and mice for 21 days and conduct tests to rule out infection [29].

PS education covered in university is deemed to be less in depth [7]. In real operations, it requires a lot of detail to explore many technical options before choosing a solution [8]. Thus, it is desirable to equip students with the skill/ability to solve problems of cost-effectiveness, safety and time. Shallcross [9] expressed that all CE students should be made aware of where to find information on safety rules, regulations and standards, employer and employee rights and responsibilities following their practising law, record keeping and reporting requirements, permit-to-work systems relating to procedures, fire prevention and protection, hazards of dealing with chemicals, toxic material and hazardous wastes (incl. biomedical hazards), hazards identification and risk minimization methods, hazards associated with maintenance procedures and recovering from process upsets, hazards related to reactive systems, safety management systems, site emergency response (e.g., hazardous material emergencies), environmental protection requirements, process control, human factors and their influence on safety, and inherently safe design.

There are various definitions of PSM created by the OSHA, Energy Institute (EI), Center for Chemical Process Safety (CCPS) and other companies or organizations suited for the operation and business needs (Table 1). Distinct keywords are common in these well-established PSM definitions, such as the following: approaches/procedures/management/framework: Prevention AccidentsIncidentsnear misseshazard control;release of chemicals/hazardous material/energy;Safety standards/practices.
