Explanation:
According to the HERARCHY of hazard control what sequence is specified for protecting workers from chemical hazards assume that one is the safest method and five is the least safest method
Answer:
Explanation:
Elimination 1
Substitution 2
Engineering Controls 3
Administrative Controls 4
PPE 5
As per the hierarchy of hazard control, the sequence is defined as safest to the least safe in five methods.
Elimination substitution engineering conrol, Administrative cotrol PPEWhat is the hierarchy of hazard control?The NIOSH defines the hierarchy for hazard control as elimination, substitution, engineering control, administrative control, and personal protective equipment.
The elimination is the physical removal of a hazard, the substitution is the replacement of the hazard, engineering control is to isolate people from the hazard, administration is changing how people work and last is to protect the work with PPE.

Explain how an electric transformer changes the voltage of the electric current. Why does a transformer work only with alternating current?
Answer:
An electric transformer is a device that uses electromagnetic induction to change the voltage of electric current. ... When alternating current passes through coil P, it magnetizes the iron core. Because the current is alternating, the magnetic field of the iron core keeps reversing.
A transformer needs an alternating current that will create a changing magnetic field.
Transformer work only on ac supply because an alternating current is needed to create a changing magnetic field.
A transformer is a static device that converts voltage or current from one level to another level.
Transformer work only on ac supply because an alternating current is needed to create a changing magnetic field. A changing magnetic field also induces a changing voltage in a coil. This is the basis of how a transformer works.
