The remaining pages in this CRST Study Guide will appear on-screen during the

test. The first two pages illustrate how to navigate the PDF that includes these

references. The remaining pages provide the content that is included in these CRST

References.

Using On-Screen References during the Test

References for each RETA test are in a PDF that appears on the screen next to test questions. The

PDF provides the following tools for locating information in the CRST References file.

• Move the red vertical line separating the two sections from side to side to assign more screen

space to the References or to questions.

• Zoom in or out to make pages in CRST References larger or smaller by clicking on the plus

(+) or minus (-) symbols at the top of the screen. This tool bar disappears after a few seconds.

The toolbar reappears when you move the mouse over the References document.

• Scroll from page to page to find the location in the References that has the table, formulas or

other information you want to use. Faster scrolling can be done by sliding the shaded market

down the column at the far right of the page.

The following screens show how this will work during the test.

Screen 1 The sample question asks about controlling an ammonia fire. The

References document title page appears on the right side of the screen.

The toolbar at the top of CRST References allows candidates to zoom in and zoom

out by clicking the plus (+) or minus (-) symbols. The toolbar disappears after a

few seconds. The toolbar reappears when the mouse moves over CRST References.

Save or print functions are disabled during the test. A candidate who clicks on

these must select “Cancel” to return to CRST References.

Do not use the CTRL + F keys for searching in the PDF as this will cause the testing

system to think a security violation is happening and will automatically log the test

taker out and the login screen will appear



Screen 2 Information to help answer the question appears in the Ammonia SDS. Scroll to

the opening page of the SDS.

Screen 3 The answer to the question appears in the first paragraph of Section 5, Fire

Equipment for

Firefighters

Fire Fighting

Procedures

Use Water Spray or Water Fog, Carbon Dioxide, Polar or Alcohol Foam,

Dry Chemical. Halon may decompose into toxic materials. Carbon dioxide

can displace oxygen. Use caution when applying halon or carbon dioxide in

confined spaces.

Gas may ignite at vapor concentrations between 16% and 25% in air.

However, ammonia-air mixtures are difficult to ignite and burn with little

vigor. In the absence of oxygen enrichment, the risk of initiating an

accidental fire or explosion is low. Do not allow ammonia vapors to

accumulate in confined areas where ignit ion may occur. Intense heating

particularly in contact with hot metallic surfaces may cause

decomposition of am m onia generating hydrogen, a flammable gas.

Stop flow of gas. Use water fog to keep fire-exposed containers cool and to

protect personnel effecting the shut-off. Wear self-contained breathing

apparatus (SCBA) and encapsulating chemical protective clothing.

Approach fire upwind and evacuate area downwind. Em ergency

responders in the danger area shou ld wear bunker gear and self-

contained breathing apparatus for fires beyond the incipient stage

(29CFR 1910.156). In addition, wear other appropriate protective

equipment as conditions warrant (See Section VIII). Isolate damage area,

keep unauthorized personnel out. Stop spill/release if it can be done with

minimal risk. If this cannot be done, allow fire to burn. Move undamaged

containers from danger area if it can be done with minimal risk. Stay away

from ends of container. Water spray may be useful in minimizing or

dispersing vapors. Cool equipment exposed to fire with water, if it can be

done with minimal risk.

Dry Chemical or carbon dioxide are recommended extinguishing media.

Stop flow of gas before extinguishing fire. Use water spray to keep fire

exposed containers cool. Extinguish fire using agent suitable for

surrounding fire.

Combustible. Wear goggles, self-contained breathing appara tus, and

rubber over clothing (including gloves). Stop flow of gas, or liquid if

possible. Let fire burn. If material involved in fire: Cool all affected containers with flooding

quantities of water. Apply water from as far distance as possible. Use water

spray to knock-down vapors. Solid streams of water may spread fire. Don

not use water on material itself. Do not apply water to point of leak in tank

car or container.

And Clean-Up

Note t hat although ammonia gas is light er than air, sudden release may

generate an aerosol of liquefied ammonia which may cling to the ground

for long distances. May ign it e in th e presence of open flames and

sparks.

Narrow lower to upper combustion range (16-25%) makes ignition

difficult. Keep all sources of ignition away from spill/release. Do not apply

water onto leaking tank. Stop the flow of gas or liquid. Use water to

protect personnel effecting the shut -off . Approach from upwind.

Evacuate the area immediately. Eliminate all open flames in vicinity of

indoor spills or released vapor. Water fog can be used to cleanse

atmosphere of ammonia vapor.

Downwind areas can be protected by water fog nozzles positioned

downwind.

Do not enter a visible cloud of ammonia. Isolate and evacuate the leak

or spill area immediately for at least 150 feet in all directions. For larger

spills, isolate at least 300 feet in all directions and then evacuate area

downwind at least 0.4 miles in width and at least 0.8 miles in lengt h.

Keep area isolated until gas has dispersed.

Dike liquid spills to contain liquid.

7. Handling and Storage

Safe Handling Contents are under pressure. The use of explosion-proof equipment is

recommended and may be required (see appropriate fire codes). Do not

enter confined spaces such as tanks or pits without following proper entry

procedures such as ASTM D-4276. Protect against physical damage.




Storage

Work/ Hygienic

Practices

Ventilation

Outside shaded area or detached storage is preferred. Inside storage

should be in a cool, dry, well vent ilat ed, noncombustible location, away

from all possible sources of ign itio n.

Avoid contact with skin and avoid breathing vapors. Do not eat, drink, or

smoke in work area. Wash hands before eating, drinking, or using

restroom. Do NOT place food, coffee or other drinks in the area where

dusting or splash in g of solut ions is possible.

Local exhaust is essential. Spark-proof fans desirable with mechan ical

ventila t ion. Ducts shou ld be located at ceiling level and lead upwards to

the outs ide. Eyewash and safety shower should be available in work area.

13. Disposal Considerations

Disposal of Container Because of the toxicity of ammonia to aquatic organisms, NEVER dispose

of or allow any ammonia or ammonia contaminated water to flow into any

surface water bodies. Surface water bodies include drainage ditches, storm

water and sanitary sewers, wetlands, ponds, lakes and streams. Diking will

contain the liquid and all ow it to stabilize. Keep unprotected personnel

away from area until it is free of ammonia. Do not apply water directly to

ammonia li quid as this will cause boiling and splattering. Soil

contaminated with ammonia or aqua ammonia may need to be excavated

and properly disposed of according to local and state regul ations.

Consult Federal, State, or Local Authorities for additional p roper disposal

procedures.
