Summary
Mining operations face hazards from large lead-acid batteries. This study suggests design modifications, like lighter lids and improved connectors, to enhance safety for battery maintenance and repair in underground coal mines.
Area of Science:
- Occupational Safety and Health
- Mining Engineering
- Battery Technology
Background:
- Large lead-acid batteries are critical for powering vehicles in the mining industry.
- Improper maintenance of these batteries poses significant mechanical and electrical hazards in underground coal mines.
Purpose of the Study:
- To investigate safety interventions for lead-acid batteries used in mining.
- To identify practical design modifications to mitigate hazards during battery maintenance and repair.
Main Methods:
- Review of the Mine Safety and Health Administration accident/illness/injury database.
- Investigation into the design and implementation of lead-acid batteries for safety.
Main Results:
- A significant number of mining injuries are linked to lead-acid battery maintenance.
- Common injuries include burns from electrical arcing, acid exposure, strained muscles, and crushed hands.
Conclusions:
- Practical design modifications can improve safety.
- Recommendations include reducing battery lid size/weight with lift assists and using five-pole cable connectors.

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...

A battery is a galvanic cell that is used as a source of electrical power for specific applications. Modern batteries exist in a multitude of forms to accommodate various applications, from tiny button batteries such as those that power wristwatches to the very large batteries used to supply backup energy to municipal power grids. Some batteries are designed for single-use applications and cannot be recharged (primary cells), while others are based on conveniently reversible cell reactions that...

Generally, a single battery is not enough to power some devices. In such cases, batteries can be combined in two ways: in series or in parallel.
In series, the positive terminal of one battery is connected to the negative terminal of another battery. Hence, the voltage of each battery is added to give the net voltage, which is increased because each battery boosts the electrons that enter it. The same current flows through each battery because they are connected in series.
