Robert M. Rioux & Suprita Jharimune, Pennsylvania State University, University Park, PA Among the many hazards present in the laboratory, electrical hazards are one of the most common we must be cognizant of since most of the laboratory equipment we use requires electricity for operation. Improper handling or operation of electrical devices might lead to electric shock with the potential risk of injury or even death. Electric sparks can lead to fire or explosion (since many flammable...

Minimally invasive surgical (MIS) procedures rely on anatomical references to localize structures not directly visible to the surgeon. This manuscript describes a combined method of plane-by-plane dissection and sectional anatomy of fresh-frozen specimens to locate the structures at risk during MIS procedures.

Surveying near highways, rough terrain, or power lines involves significant risks. Working along highways is particularly dangerous and requires the use of warning signs and flagmen. It is safest to avoid working directly on roads and use offsets whenever possible. When highway work is unavoidable, it must follow all safety guidelines. Surveyors should wear bright clothing, such as orange reflective vests, to ensure visibility to motorists, coworkers, and hunters. In construction zones, wearing...

Source: Ali Bazzi, Department of Electrical Engineering, University of Connecticut, Storrs, CT. Electric machines and power electronics experiments involve electrical currents, voltages, power, and energy quantities that should be handled with extreme diligence and care. These may include three-phase AC voltage (208 V, 230 V, or 480 V), up to 250 V DC voltages, and currents that can reach 10 A. Electrocution occurs when an electrical path is established through the body with very low currents...
FAQs
Assessment should consider flammability, toxicity, corrosivity, and reactivity, because each property can create different pathways to harm. The review should also include possible exposure routes, along with the behavior of the reaction, equipment, and procedure under planned conditions. Examining these factors together helps reveal risks that may not be apparent from considering a substance alone.
Qualitative assessment organizes risks using descriptive judgments about likelihood and severity, while quantitative assessment uses numerical estimates when suitable information is available. Both approaches help determine which hazards require the greatest attention. Applying either approach before work begins supports decisions about experimental planning, control selection, and the allocation of safety resources.
These controls reduce risk by addressing hazards or limiting the opportunity for exposure. Substitution can replace a more hazardous material or approach, containment separates the hazard from people, and ventilation helps manage airborne exposure. Personal protective equipment provides an additional protective measure. Selecting controls based on the identified hazard strengthens prevention rather than relying only on emergency response.
Before work starts, review the substances, intended reactions, equipment, and detailed procedures. Consider hazardous properties, potential exposure routes, and conditions that could produce harm, then evaluate likelihood and severity. This advance review allows researchers to select suitable controls and prepare the workspace before the experiment creates an active chemical hazard.
Risk findings can guide how laboratories are arranged and how chemicals are stored. Identifying flammability, toxicity, corrosivity, reactivity, and exposure concerns helps determine where controls such as containment and ventilation are needed. The same information supports safer storage decisions and reduces the chance that incompatible conditions, equipment use, or routine handling will create preventable harm.
A prior review of hazards and exposure routes helps researchers anticipate the types of incidents an experiment could produce. Linking those findings to the severity and likelihood of harm supports more appropriate emergency planning. In practice, this preparation can limit exposure and improve readiness for accidents involving hazardous substances, reactions, equipment, or procedures.
