What type of confined space has the normal hazards presented by a confined space plus additional hazards?
PIT_PIT [208]
Hello,

The answer is option A "<span>Permit-required".

Reason:

A permit-required is the confined space in which normal hazards are presented plus other hazards. Its not option B because the answer would not be hazard because there talking about additional hazards and confined spaces (probably safe rooms). Its also not option C because characteristic is a type but its describing a type of hazard its not a way to confine it.

Describe and name the parts of the atom.
Cerrena [4.2K]

Answer:

Elements, such as helium, depicted here, are made up of atoms. Atoms are made up of protons and neutrons located within the nucleus, with electrons in orbitals surrounding the nucleus.

The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge). The outermost regions of the atom are called electron shells and contain the electrons (negatively charged).

The model of the atom can be broken down into three constituents parts – protons, neutron, and electrons. Each of these parts has an associated charge, with protons carrying a positive charge, electrons having a negative charge, and neutrons possessing no net charge.
