Radioactive decay is such a spontaneous exothermic nuclear reaction in which the Q-value energy is converted into the kinetic energy of the products.

Radioactive decay is the process in which the nuclei of radioactive atoms emit charged particles and energy, which are called by the general term radiation. Radioactive atoms have unstable nuclei, and when the nuclei emit radiation, they become more stable.

Of course, nuclear reactors ultimately get their energy from nuclei. This nuclear energy is potential energy stored inside the nucleus of an atom. The protons and neutrons inside of the nucleus are held together by the strong nuclear force, which balances the repulsion of the Coulomb force between the protons.

The energy and matter released during radioactive decay is called nuclear radiation, and it takes on the following two principle forms: Particulate radiation consists of actual subatomic particles being emitted from the nucleus of the atom. The second type is called electromagnetic radiation.

The skull and crossbones symbol means the product is poisonous. Licking, eating, drinking, or smelling a substance marked with this symbol can make you very sick or even cause death.

1a : clover sense 1 broadly : any of several leguminous herbs (such as bird’s-foot trefoil) with leaves that have or appear to have three leaflets. b : a trifoliolate leaf. 2 : an ornament or symbol in the form of a stylized trifoliolate leaf.

There are 9 hazardous substances symbols you need to know: flammable, oxidising, explosives, gas under pressure, toxic, serious health hazard, health hazard, corrosive and environmental hazard.

The category tells you about how hazardous the product is (that is, the severity of hazard).

• Category 1 is always the greatest level of hazard (that is, it is the most hazardous within that class).
• Category 2 within the same hazard class is more hazardous than category 3, and so on.

Exploding Bomb: Explosives, including organic peroxides and highly unstable material at risk of exploding even without exposure to air (self-reactives). Flame Over Circle: Identifies oxidizers.

List of Explosive Materials

• A. Acetylides of heavy metals. Aluminum containing polymeric propellant.
• B. Baratol. Baronol.
• C. Calcium nitrate explosive mixture.
• D. DATB [diaminotrinitrobenzene]
• E. EDDN [ethylene diamine dinitrate]
• F. Flash powder.
• G. Gelatinized nitrocellolose.
• H. Heavy metal azides.

Usually you will see the triangle with the explosive symbol inside it. Examples include aerosol cans, such as hair spray or spray paint. Product is corrosive and will burn skin, eyes, throat, or stomach. Examples include oven cleaner and toilet bowl cleaner.

These 4 important safety signs can be broken into categories: Prohibition, Warning, Mandatory and Emergency.

YELLOW

Yellow

Red colours are used to identify locations of danger, fire protection equipment and apparatus, stop buttons and emergency stop controls. Yellow colours are used to identify when areas of caution should be exercised as well as cautionary notes of a general nature.

There are four types of wayfinding signs: identification, directional, informational, and regulatory. As standalone signs, they serve a specific role; as part of the greater wayfinding system, they inform each other.

WARNING

The color of safety

• Red: Fire protection equipment. Danger, high risk of injury or death.
• Orange: Moderate risk of injury. Guarding devices.
• Yellow: Caution statements. Minor risk of injury.
• Green: Safety equipment or information.
• Blue: No immediate hazard.
• Red – combustible materials. Yellow – oxidizers.

Red is the color of fire and blood, so it is associated with energy, war, danger, strength, power, determination as well as passion, desire, and love.

Red

The hexadecimal color code #167cb9 is a shade of cyan-blue. In the RGB color model #167cb9 is comprised of 8.63% red, 48.63% green and 72.55% blue. In the HSL color space #167cb9 has a hue of 202° (degrees), 79% saturation and 41% lightness.

Safety Color Coding Labels and Tape

Section 6E-3 (High Visibility Clothing) states in part: For daytime work, the flagger’s vest, shirt, or jacket shall be orange, yellow, strong yellow green or fluorescent versions of these colors. For nighttime work, similar outside garments shall be retro reflective.

Fluorescent lime, orange, and red are the three approved background color options for high-visibility clothing. Retroreflective tape that reflects light in the direction of its source, such as a vehicle’s headlights, thereby illuminating a worker in low light or at night.
