HAZARD SYMBOLS

7/31/2019 MSDS MHK

http://slidepdf.com/reader/full/msds-mhk 13/21

DEFINITIONS  Flammable: ANY substance

easily ignited and quick burning, including liquids with a flash pointbelow 95 degrees Fahrenheit.

Toxic: ANY substance (alone

or via chemical reaction) ableto cause harm/produce injuryto the body throughabsorption, ingestion,

inhalation, or injection. Caustic: ANY substance able

to burn, damage or destroyorganic tissue by chemical

reaction; Corrosive.

DEFINITION CONT’D 

Flash point--the lowesttemperature at which a liquidproduces enough vapor toignite.

Density--(% of Water & Air);Specific Gravity

7/31/2019 MSDS MHK

http://slidepdf.com/reader/full/msds-mhk 15/21

DEFINITION CONT’D 

PEL – -Permissible Exposure Limit is the 

standard recognized by industry as the maximum amount or concentration of achemical that a worker may be exposed to.

TLV  — Threshold Limit V alue is arecommended limit for chemical substance

exposures, similar to the PEL but most oftenmore restrictive than the PEL.

TWA – -an 8-hour Time-Weighted Average is the concentration the average worker canbe exposed during an 8-hour workday, dayafter day, without harmful effects.

STEL —  “Short Term Exposure Limit” is a15 minute period.

Ceiling—the maximum (C) concentrationnever to be exceeded.

DEFINITION CONT’D 

Lethal Dose50 (LD50) is theamount of a substance that,when administered by a definedroute of entry (e.g. oral ordermal) over a specified periodof time, is expected to cause

the death of 50% of a definedanimal population.

DEFINITION CONT’D 

Lethal Concentration50 (LC50) isthe amount of a substance inair that, when given byinhalation over a specifiedperiod of time, is expected tocause the death in 50% of a

defined animal population.
