Air pollutant

Air pollution

Definition

The American Conference of Governmental Industrial Hygienists organization in the

United States.

Sampling for pollutants in the air using a variety of means such as sorbent tubes, bags, filters and sampling conventions.

Any substance in air that could, in high enough concentration, harm man, other animals, vegetation, or material. Pollutants may include almost any natural or artificial composition of airborne matter capable of being airborne. They may be in the form of solid particles, liquid droplets, gases, or in combination.

Air pollution are chemicals present in the atmosphere which are normally not a part of the atmosphere. Basically, air pollution is air that is contaminated, interferes with human health or welfare, or harms the environment. Some examples include dust, smoke, and a variety of toxic gases such as carbon monoxide.

Air quality monitoring Sampling, measurement/analysis of airborne pollutants.

Air quality standards The level of pollutants prescribed by regulations that are not to be exceeded during a given time in a defined area.

Airborne particulates

ASHRAE

Total suspended particulate matter found in the atmosphere as solid particles or liquid droplets. Chemical composition of particulates varies widely, depending on location and time of year. Airborne particulates include: windblown dust, emissions from industrial processes, smoke from the burning of wood and coal, and motor vehicle or non-road engine exhausts.

The American Society of Heating, Refrigeration and Air-Conditioning Engineers in the

Bump Test

Calculating particulate matter

Ceiling

Confined Space (see also “Permit Required

Confined Space”)

A functional test of the sensors installed in the gas monitor. Calibration gas is used for a bump test.

The worker exposure assessment, on the EVM, is based on a gravimetric analysis with filter samples drawn over a period time. If acute effects exist from personal inhalable dust, the sampling analysis allows for short term analysis (STEL).

This is the maximum allowable concentration of a chemical that an employee may be exposed to. It must never be exceeded, even for an instant.

A “Confined Space” has three components: a.

It is large enough to enter & perform work b.

It has limited means for entry & exit c.

It is not designed for continuous occupancy

Definition

This is the correction override factor that is applied during your run or after a run for particulate measurements or PID (VOCs) measurements. In DMS, an override factor can be applied after a run via the Correction Override icon. The applied dust override is displayed in the General Data Panel (if selected under the sensor data list).

The dew point measurement is the absolute measurement of the amount of water vapor in the air (indicating how much humidity is in the air). It is also defined by

Wikipedia as, “the temperature to which a given parcel of air must be cooled, at constant barometric pressure, for water vapor to condense into water. The condensed water is called dew. The dew point is also referred to as the saturation point”.

Is a percentage of signal loss of a gas sensor per month.

This is required to cover a sensor socket when no sensor is present to maintain unit to environment sealing capability.

When setting up the Dust profile in DMS, there is an active profile field. The Dust

Override profile field corresponds with the active (or applied) dust profile.

Dust is typically known as a type of particulate matter or an aerosol with a miniscule diameter of 0.1 μm upwards.

This is the surrounding of a person by finely divided solids or a liquid. A worker in a storage tank filled with sawdust, for example, could fall into an air pocket, be completely surrounded by sawdust, and suffocate to death.

There is a high cross-sensitivity between CO and H

S.

A term for the three components required to start a fire: fuel, oxygen, and ignition.

Describes an analytical chemistry methodology for determining the quantitative mass of a solid. The EVM collects particulates in an internal gravimetric sample holder that are filtered, collected, and weighed to determine the severity of the worker exposure.

Term Definition

Hazardous Atmosphere Means an atmosphere presenting a potential for death, disablement, injury, or acute illness from one or more of the following causes: a.

A flammable gas, vapor or mist in excess of 10% of its' lower explosive limit (LEL).

b.

An oxygen deficient atmosphere containing less than 19.5% oxygen by volume or an oxygen enriched atmosphere containing more than 23.5% oxygen by volume.

c.

Airborne combustible dust at a concentration that meets or exceeds its LEL (airborne combustible dust which obscures vision at five feet or less).

d.

An atmospheric concentration of any substance for which a dose or a permissible exposure limit is published in Subpart G, Occupational Health and Environmental

Control , or in subpart Z, Toxic and Hazardous Substances, which could result in an employee exposure in excess of its dose or permissible exposure limit, and that could cause death, incapacitation, impairment of ability to self-rescue, injury or acute illness.

e.

Any other atmospheric condition that is immediately dangerous to life or health

(IDLH).

IDLH (Immediately

Lockout-Tagout

Material Safety Data

Sheet

Any condition that poses an immediate or delayed threat to life, or that would cause irreversible adverse health effects or that would interfere with an individual's ability to escape unaided from a confined space.

Placing locks or tags on the energy-isolating device (e.g. breaker boxes, control switches, valves, etc.) to prevent the unauthorized re-energization of the device or circuit while work is being performed by personnel. Tags shall indicate that the energy-isolated device must not be operated until the tag is removed by the individual(s) that installed the tag.

Published for every chemical or substance that may be hazardous; if an exposure limit has been published for a substance being discussed in an MSDS, that limit, such as TWA or PEL, is required to be included in the MSDS publication. Ref: 29

CFR 1910.1200 (g)(2)(i)(C)(2) and (g)(2)(vi). TWA's and PEL's are not available for most chemicals. There are simply too many chemicals, many of which have not gone through the rigorous scientific study and peer review required. The absence of an exposure limit for a substance should not be used to assume that a substance is not hazardous.

Measurement parameters

MSHA

NIOSH

Definition

The following measurements are displayed on the instrument and in the Logged data table/chart in DMS.

Average The measurement value over the time interval (or logging interval)

Level

Minimum

The instantaneous measurement at a specific point in time.

The minimum measurement over the time interval (or logging interval).

Maximum

STEL (Short term

Exposure Limit)

The maximum measurement over the time interval (or logging interval).

The maximum concentration above the time-weighted average that employees can be exposed to over a specific time period

(usually 15 minutes) no more than four (4) times per day. (See

PEL for more information.)

TWA Most permissible exposure limits are based upon an 8-hour time weighted average (TWA). The air concentration may sometimes go above the TWA value, as long as the 8-hour average stays below. (See PEL for more information.)

The National Institute for Occupational Safety and Hygiene in the United States. An organization dedicated to investigating the harmful effects of varied industrial hazards on the working population and promulgating regulations to control their harmful effects.

OSHA The Occupational Safety and Health Administration in the United States. A division of the Department of Labor charged with dealing with the health and welfare of the working population that issues guidelines and legislation to control the hazards at work.

Particulate matter (PM) Particulate matter, [also referred to as total suspended particles (TSP)] consists of tiny inhalable dust which can be man-made or natural. A wide range of particulates include the following pollutants: road dust, the burning of fossil fuel, diesel soot, environmental fires (forest or grassland), power plants, and wood smoke. These particles are a mixture of visible and microscopic solid particles and tiny liquid droplets referred to as aerosols.

Thoracic dust PM10 is the fraction of PM containing particles that are small enough to pass the PM10 impactor (10 mm)

Respirable dust The cut-points for respirable dust are: PM4 (4 microns), PM2.5

PEL (Permissible

Exposure Limit)

Photodiode ppm/ppb

Definition

The highest level of toxic gas or oxygen reached while the unit is on.

Permissible exposure limit. PEL's are a regulatory limitation to exposure used to specify the allowable exposure to a substance in the workplace and assume that the exposure takes place over an 8-hour shift in a 40-hour work week. Note that there are more stringent exposure limits for higher levels of exposure that may occur over a shorter time interval.

There are three types of PELs:

TWA Most permissible exposure limits are based upon an 8-hour time weighted average (TWA). The air concentration may sometimes go above the TWA value, as long as the 8-hour average stays below.

(NOTE: This measurement is not applicable with temperature. relative humidity, or air velocity sensors.)

Ceiling Limit The maximum allowable concentration of a chemical that an employee may be exposed to. It must never be exceeded, even for an instant.

STEL The Short Term Exposure Limit (STEL) is the maximum concentration above the time-weighted average that employees can be exposed to over a specific time period (usually 15 minutes) no more than four (4) times per day. This stands for Short Term

Exposure Limit and is the maximum average concentration of a toxic gas to which an unprotected worker may be exposed over any fifteen-minute interval during a work period. The EVM calculates the

STEL by compiling fifteen one-minute averages, and updates that average each minute after the initial fifteen-minute exposure. If the

STEL is reached or exceeded, the alarm activates, and the STEL enunciator turns on.

Different regulatory agencies have different acronyms for PELs:

NIOSH (National Institute for Occupational Safety and Health) uses

REL (Recommended Exposure Limit), and ACGIH (American

Conference of Governmental Industrial Hygienists) uses TLV

(Threshold Limit Value).

(NOTE: This measurement is not applicable with temperature. relative humidity, or air velocity sensors.)

A type of photodetector that is able to convert light source into either current or voltage. With the EVM, it is used to measure the amount of light scattered from a particle cloud.

Parts per million (or parts per billion) of concentration of the gas of interest in air. For example, 1 ppm signifies one part of gas to 1 million parts of air.

Definition

Exposure limits set by the National Institute for Occupational Safety and Health

The relative humidity of an air-water mixture is defined as the ratio of the partial pressure of water vapor in the mixture to the saturated vapor pressure of water at a prescribed temperature. This can be calculated by dividing the temperature and dew point readings and multiplying by 100%.

Toxic and LEL sensors are calibrated to detect a specific gas. However there may be some cross-sensitivity of the sensor to other toxics or combustibles.

Point in time when the maximum exposure will occur from the beginning of any 8hour period

Threshold limit value: the level of exposure that a worker can experience in the workplace without an unreasonable risk of disease or injury. These are not estimates of "level of risk" for different exposure levels nor do they address the different means by which a person may be exposed to a substance. TLV's are specified by ACGIH, the American Conference of Government Industrial Hygienists. TLV's are guidelines prepared by ACGIH and are solely concerned with health risk. They do not address economic considerations. TLV's are not regulatory but rather are advisory. (See PEL and TWA which are specified by OSHA).

A type of air pollution that is a carbon-containing chemical, which is typically vaporized at ambient temperatures. Some examples of VOCs include: biological agents (mold, dust, mites…etc.), carbon monoxide, formaldehyde, second hand tobacco smoke. On the EVM, VOCs are measured in air by using the Photoionization detection (PID) sensor.
