Keep a cool head and follow these safety tips when
performing hot work.

Each year, welding and cutting operations yield
many of the reported accidents at aggregate mines. Potential health and
safety hazards result from sparks, hot metal and radiant energy, and the
fumes and gases produced during this work. Equipment may generate high
voltages or use compressed gas, and thus, require special awareness and
training.

To safeguard workers, pay attention to the
following items.

• Slag: Injuries caused by burns during
  welding and cutting operations result when slag, the hot metal byproduct
  of the processes, lands on workers. Ears are primary targets, but
  unprotected skin in other body areas such as between sleeves and gloves
  and between pants and boots can also be hurt when they come in contact
  with hot surfaces or hot loose metal. Slag may fly, fall, drip, or ooze
  as work is executed.

• Intense heat: Unexpected and irregular
  flash or arc burns can hurt exposed skin. The harm and pain from these
  burns usually worsens throughout time.

• Intense light: Bright flashes of
  ultraviolet light cannot only burn skin, but also the lens of the eye.
  Damage may occur instantly or gradually throughout time if protective
  eyewear is not worn and if it is not appropriate for the intensity of
  the light.

• Inadequate preparation: If metal
  objects being welded or cut have not been properly aligned and secured
  before work begins, they may slip, cutting or pinching workers as they
  try to make adjustments as they work.

• Harmful fumes: Burning metal and
  metal-bearing materials, especially those containing lead or cadmium,
  may release highly toxic chemicals into the air. Employers must check
  that ventilation is adequate in work areas before any welding or cutting
  begins. Mechanical ventilation or individual respirators will work in an
  area that may be in a confined space cut off from natural ventilation.

• Electric shock: Any electric welder can
  cause electrocution if the electrode touches exposed skin while the
  worker is grounded. Shock can cause involuntary muscular contractions
  and even death.
