SOLUTIONS
Welding curtain - Answer-A protective screen set up around a welding operation
designed to safeguard workers not directly involved in that operation.
Flash burn - Answer-The damage that can be done to eyes after even brief exposure to
ultraviolet light from arc welding. A flash burn requires medical attention.
heat, oxygen, fuel - Answer-Fire has been described as having three components
Permit-required confined space - Answer-A confined space that has been evaluated
and found to have actual or potential hazards, such as a toxic atmosphere or other
serious safety or health hazard. Workers need written authorization to enter a permit-
required confined space.
Lockout/tagout (LOTO) - Answer-A formal procedure for taking equipment out of service
and ensuring that it cannot be operated until an authorized person has removed the lock
and/or warning tag.
Ground Fault Circuit Interrupter (GFCI) - Answer-A device that interrupts and de-
energizes an electrical circuit to protect a person from electrocution.
Proximity work - Answer-Work done near a hazard but not actually in contact with it.
arc welding - Answer-The joining of metal parts by fusion, in which the necessary heat
is produced by means of an electric arc.
Silicosis - Answer-A serious lung disease resulting from the inhalation of crystalline
silica particles.
chronic obstructive pulmonary disease (COPD) - Answer-Lung disease that results in
the obstruction of lung airflow and interferes with normal breathing.
Clean rooms - Answer-A room or area that is used for scientific research or specialized
processes, such as the manufacture of pharmaceuticals and semiconductors.
Wind sock - Answer-A cloth cone open at both ends mounted in a high place to show
which direction the wind is blowing
, Welding curtains - Answer-protective screens set up around a welding operation
designed to safeguard workers not directly involved in that operation
Brazing - Answer-A process using heat in excess of 800 degrees F to melt a filler metal
that is drawn into a connection. Commonly used to join a copper pipe.
Flash point - Answer-The temperature at which a fuel gives off enough vapor to burn
Qualified person - Answer-A person who, by possession of a recognized degree,
certificate, or professional standing, or by extensive knowledge, training, and
experience, has demonstrated the ability to solve or prevent problems relating to a
certain subject, work, or project.
Less turnover - Answer-A company with strong saftey culture has characteristics such
as, fewer at-risk behaviors, lower incedent and accident rates, lower absenteeism,
higher productivity and "_________"
The "fatal four" includes, struck by hazards, caught in or caught between hazards,
electrical hazards, and "_________" - Answer-Falls
Informational sign - Answer-These specific signs are blue and typically indicate "no
admittance", "no tresspassing", and "for employees only"
Safety sign - Answer-These signs are white most have a green panel with white letters
they typically indicate "first aid stations", "emergency eye wash stations", "evacuation
routes" and "safety data sheet (SDS) stations"
Equipment or clothing designed to prevent or reduce injuries. - Answer-Personal
Protective Equipment (PPE)
Hazard Communication (HAZCOM) Standard - Answer-The Occupational Safety and
Health Administration standard that requires contractors to educate employees about
hazardous chemicals on the job site and how to work with them safely.
Containers - Answer-Oily rags must be stored in
Job Safety Analysis (JSA) - Answer-Task safety analysis (TSA) is similar to...
Safety Data Sheet (SDS) - Answer-A document that must accompany any hazardous
substance. It identifies the substance and gives the exposure limits, the physical and
chemical characteristics, the kind of hazard it presents, precautions for safe handling
and use, and specific control measures.
Competent person - Answer-A person who is capable of identifying existing and
predictable hazards in the surroundings or working conditions that are unsanitary,
