Chapter 13 Fire Hose Review Questions

Question 1

List 3 methods to prevent mechanical fire hose damage.

Answer 1

Common Examples of Mechanical Damage are : slices, rips, and abrasions on the coverings, crushed or damaged couplings, and cracked inner linings

_To Prevent _

1. Avoid laying or pulling hose over rough, sharp edges, or objects
2. Use hose ramps or bridges to protect hose from vehicles running over it
3. Open and close nozzles,valves,and hydrants slowly
4. Change position of folds in hose when reloading it on apparatus
5. Provide chafing blocks to prevent abrasion to hose when it vibrates near the pumper
6. Avoid excessive pump pressure on hoselines

Question 2

List 3 methods to prevent Thermal fire hose damage

Answer 2

Thermal damage is char, melting, or weakening as well as dehydrating , freezing does damage as well

To Prevent

1. Protect hose from exposure to excessive heat or fire when possible
2. Do not allow hose to remain in any heated area after it is dry
3. Use moderate temperature for mechanical drying. A current of warm air is much better than hot air
4. Keep the outside of woven-jacket fire hose dry when not in use
5. Run water through hose that has not been used for some time to keep the liner soft
6. Avoid laying fire hose on hot pavement to dry
7. Roll dry hose in a straight roll for storage. This keeps the liner from drying out
8. Prevent hose from coming in contact with, or being in close proximity to, vehicle exhaust systems
9. Use hose bed covers on apparatus to shield the hose from the sun

Question 3

List 3 methods to prevent Organic fire hose Damage

Answer 3

Organic Damage is mildew/mold

To Prevent

1. Remove all wet hose from the apparatus after a fire and replace with dry hose
2. Inspect, wash, and dry hose that has been contaminated in any way
3. Remove, inspect, sweep, and reload hose if it has not been unloaded from the pparatus during a period of six months. Make sure that the hose is folded at different points than when previously loaded
4. Inspect and test hose annually and after possible damage

(pg. 636)

Question 4

List 3 methods to prevent Chemical fire hose Damage

Answer 4

Chemical Damage such as exposure to petroleum products, pints, acids or alkalies may weaken the hose to the point of bursting under pressure. Can cause seperation of rubber lining with inner jacket.

To Prevent

1. Scrub hose thoroughly and brush all traces of acid contacts with a solution of baking soda and water. Baking soda neutralizes acids
2. Remove hose periodically from the apparatus, wash it with plain water, and dry it thoroughly
3. Test hose properly if there is any suspicion of damage
4. Avoid laying hose in the gutter or next to the curb where vehicles have been parked becaus of possible accumulations of oil from their mechanical components and acid from batteries
5. Dispose of hose according to departmental SOP if it has been exposed to hazardous materials and cannot be decontaminated
