CHAPTER 18

SURFACE PRESERVATION

Just about everyone has been involved in cleaning,

preserving, and maintaining something. Painting the

family home or washing and waxing your car are good

examples. What you did was to protect a surface from

the effects of weather or exposure, to extend its lifetime,

and to improve its appearance.

The U.S. Navy has a far greater problem because all

Navy ships operate in a much harsher environment than

your home or car. Constant exposure to the sea and

saltwater corrosion can quickly turn the exterior of a

ship into a mass of rust. Interior spaces have their

problems as well. Constant changes in the weather and

in the surrounding water temperature cause moisture,

humidity, and chemical reactions that affect electrical

systems and machinery. To overcome these harsh

conditions, the Navy expends a great deal of time,

effort, and money applying surface preservatives. These

preservatives range from detergent and fresh water to

paint and lubricants. How well these preservatives work

depends on you.

CLEANING

Learning Objectives

: When you finish this chapter,

you will be able to-

*

Recognize the purpose of cleaning and

preserving.

*

Identify the cleaning bill.

*

Recall the purpose of compartment cleaning,

sweepers, cleaning process, field day, and zone

inspections.

Maintaining clean conditions aboard ship and

ashore is an important job. Cleaning involves practically

every member, from the compartment cleaner to the

inspecting officer. Navy life requires each of us to have a

personal interest in our living and working areas, not

only for the sake of appearance but for our health and

safety as well.

THE CLEANING BILL

Each area of the ship is divided into various

departments for upkeep. The Cleaning, Preservation,

and Maintenance Bill describes these areas and outlines

the department that is responsible for them. This bill is

carefully planned to make sure all interior areas and

exterior areas of the ship's hull are assigned to personnel

for upkeep and that no areas overlap or are left out. Each

division within the department assigns its personnel to

the spaces it's responsible for. Division personnel carry

out the duties of cleaning, preserving, and maintaining.

COMPARTMENT CLEANING

The term

compartment cleaner

generally applies to

persons assigned to clean living or berthing

compartments or spaces, such as passageways and

heads. If you are assigned compartment cleaner duties,

you will be responsible for keeping your spaces clean,

preserved, and in good order. Newly assigned personnel

are closely supervised to make sure they understand

what to clean and how to clean it. Items, such as

electrical and mechanical devices, might be unfamiliar

to you. These types of items are located in almost every

space aboard ship. With this in mind, caution must be

observed at all times. Ask your supervisor to point out

any hazardous items located in your compartment and

observe all special cleaning instructions.

Cleaning gear is stocked in and issued from the first

lieutenant's storeroom. Each division is periodically

issued cleaning gear and is then responsible for its

proper stowage and care. Because cleaning compounds

and solvents are often flammable or toxic, or both, they

must

never

be left unattended or improperly stowed.

You should always read warning labels and follow their

directions carefully. Gear, such as brooms and swabs

(mops), must be cleaned after each use and placed in

their stowage racks. Gear adrift, such as rags, clothing,

or personal gear, must be "policed up" immediately. If

left adrift, these items are a tripping or fire hazard-or

worse, they might clog up dewatering equipment if the

space were flooded.

SWEEPERS

"Sweepers" is piped shortly after reveille, before

the end of the regular working day, and at other times as

scheduled. At these times, all persons assigned as

sweepers draw their gear and sweep and swab down

their assigned areas. All trash and dirt are picked up in a

dustpan and placed in a trash receptacle.

NOTE

If dirt is swept over the side, the wind may blow

it back on board or the dirt may stick to the side

of the ship. In either case, additional work is

necessary to clean the ship.

At this time you should empty all butt kits (make

sure no butts are still burning) and trash receptacles as

instructed.

Never

dump trash or garbage over the side of

the ship without first obtaining permission from the

officer of the deck. At times, all trash must be kept in a

safe area aboard the ship until it can be properly

removed.

CLEANING PROCESS

Dirt, soil, and contamination all describe the same

thing-a foreign material on a surface where it is not

wanted. Soil includes grease, oil, tarnish, rust, food

residue, and stains. Most exposed surfaces that have

been soiled may be cleaned with the proper use of

cleaning agents.

Detergents are materials that have the ability to

remove contamination and soil. There are other ways of

cleaning besides using detergents or cleaning

compounds. These include purely mechanical

processes, such as removing rust from steel by sand-

blasting or cleaning decks by sweeping. For many

cleaning problems, chipping, sweeping, sanding, or

brushing may be needed. However, when detergent

compounds are coupled with the mechanical action, a

cleaner surface is usually produced with less time and

work.

The steps used in most detergent cleaning

operations are as follows:

1. Wetting-The soil and the surface of the object

being cleaned must be wetted. If the surface is not

wetted properly, cleaning results will be poor. Contrary

to popular belief, water has very poor wetting

properties. Its wetting ability, and therefore its cleaning

ability, is improved by adding other materials, such as

soap or synthetic detergents. Adding soap or synthetic

detergents cause the water to flow into tiny crevices and

around small particles of soil.

2. Scrubbing-Dirt is loosened by the mechanical

action of rubbing or scrubbing. For example, oil

droplets are emulsified; that is, they are coated with a

thin film of soap and prevented from recombining, and

then they rise to the surface. In a somewhat similar

manner, solid particles are suspended in solution.

3. Rinsing-Rinsing is very important. Rinsing

removes loosened dirt from the surface along with the

cleaning material.

FIELD DAY

Field day is cleaning day. Periodically, a field day is

held. All hands "turn to" and thoroughly clean the ship

inside and out, usually in preparation for an inspection.

Fixtures and areas that sometimes are neglected during

regular sweepdowns (overhead cables, piping, corners,

spaces behind and under equipment, and so on) are

cleaned. Bulkheads, decks, ladders, and all other

accessible areas are scrubbed. Knife edges and door

gaskets are checked; any paint, oil, or other substances

are removed; all brightwork is shined; and clean linen is

placed on each bunk. Field days improve the appearance

and sanitary condition of the ship, aid in the

preservation of the ship by extending paint life, and

reduce the dirt intake caused by operating equipment.

Because of weather conditions, there are many days

at sea when the ship's topside areas can't be cleaned. At

the first opportunity, all topside surfaces are cleaned

with freshwater and inspected for signs of rust and

corrosion. If such signs are discovered, you should tend

to the area immediately. A little work at that time will

save you a lot of work later.

DECK COVERS

Aboard ship, deck coverings get more wear than

any other material. Unless deck coverings are properly

cared for, costly replacement is required. There are

several materials used for covering decks, but only two

types are covered here. These are the resilient and the

nonslip (nonskid paint) types.

Resilient deck coverings

include vinyl tile, vinyl

asbestos tile, and linoleum. These deck coverings do not

need painting; however, daily sweeping and wiping

away spills as soon as possible are required. Resilient

deck covering is clamped down (cleaned with a damp

swab) frequently, allowed to dry, and then buffed with a

buffer. For more thorough cleaning when the deck is

unusually dirty, apply a solution of warm water and

detergent with a stiff bristle brush or buffer and rinse

with clean water to remove residual detergent. Stubborn

dirt and black marks left by shoes can be removed by

rubbing lightly with a scouring pad, fine steel wool, or a

rag moistened with mineral spirits.

After the deck covering is washed and dried, it can

be polished (with or without waxing) with a buffer, or it

may be given a coat of self-polishing wax and allowed

to dry without buffing. Deck coverings can be buffed

several times before rewaxing.

No wax should be applied to the deck when the ship

is going out to sea or when heavy weather is anticipated.

This is an added precaution against slipping, even

though the approved floor waxes are designed to be slip

resistant.

Nonslip (nonskid paint) deck coverings

contain

pumice, which provides a better footing. To clean a

nonskid painted deck, use a cleaning solution of

detergent and dishwashing compound. To make the

solution, mix 1 pint of detergent and 5 tablespoons of

dishwashing compound. You can mix this compound

with freshwater to make 20 gallons of cleaning solution.

Apply the solution with a hand scrubber, let it soak for 5

minutes, and then rinse with freshwater.

Don't

wax or

paint nonskid deck coverings. Waxing or painting

reduces their nonskid properties.

NOTE

If it becomes necessary to spruce up the

appearance of a nonskid deck cover, brush it

with deck paint diluted with mineral spirits.

The diluted paint should be as thin as possible

so that the nonskid properties are not affected.

ZONE INSPECTION

Frequent inspections are held to make sure that all

spaces, machinery, and equipment are in a satisfactory

state of operation, preservation, and cleanliness. One

type of inspection, the zone inspection, divides the ship

or station into various sections. Each zone is then

assigned to an inspection party or team. Usually the CO

will head one team, while an officer or chief petty

officer will head each of the remaining teams. If you are

assigned to present a compartment, you present the

space to the inspecting officer by saluting and greeting

the inspector in the following manner: "Good morning

(afternoon), sir/ma'am; Seaman Apprentice Frost (your

rank and name) standing by compartment (name or

number), for your inspection, sir/ma'am." You will then

stay with the inspecting officer during the inspection of

your spaces to answer questions and provide assistance.

Such things as stowage cabinets, lockers, and drawers

should be unlocked before the inspection for easy

access. Usually the inspecting officer will give an

overall grade to the space; for example, a grade of

outstanding would indicate that no new discrepancies

were noted and all previous discrepancies have been

corrected. You can be proud of an outstanding grade.

CLEANING SOLVENTS

Learning Objectives: When you finish this chapter, you

will be able to-

*

Identify types of cleaning solvents.

*

Recall the precautions to be followed when

working with cleaning solvents.

No matter what the job, from paint removal to

swabbing the decks, take precautions against

carelessly using cleaning solvents. Look at the

following example:

Seaman Joe Frost didn't read the labels on the

chlorine-based cleaning material he was using

to clean the commode. He decided to clean the

drains at the same time and added a granulated

drain cleaner to the chlorine-based cleaner.

Then he left the head. A few minutes later he

heard a loud explosion. The reaction between

the chlorine-based cleaner and granulated

cleaner caused the explosion. Luckily, no one

was hurt, but the head was a mess.

Solvents used in paints, adhesives, rubber and

plastic materials, and degreasing solutions are

hazardous to your health. Most solvents are toxic and,

with a few exceptions, are flammable. Take the

appropriate measures to reduce their toxic and

flammable effects. In addition, solvents that come in

contact with your skin can cause serious skin problems.

When using solvents, always observe the following

precautions:

*

Make

sure the space in which you are working

has adequate ventilation.

*

Wear

protective clothing, goggles, respirators,

gloves, and other appropriate equipment.

*

Make

sure accessible fire-fighting equipment is

nearby.

*

Take

every precaution to prevent excessive

vapors from contaminating the air.

*

Check

the labels on all containers of liquids.

*

Wipe

up spilled solvents immediately.

*

Avoid

contact with your eyes, skin, or clothing.

*

Never

swallow solvents.

*

Avoid

breathing the vapors.

*

Keep

solvent containers tightly closed when you

are not using them.

*

Check

containers for leakage.

*

Transfer

solvents from a defective/leaking

container to a new container.

*

Make

sure containers are empty before you

discard them. You must observe the approved

practices for disposal of solvents, cleaners, and

their containers.

*

Label

all containers used to store solvents.

and comply with all instructions and

precautions on the label.

PRECAUTIONS

Always follow safety precautions when working

with solvents.

Never

use solvents in an unventilated

space under any circumstances. Special clothing

requirements also must be observed when using some

solvents.

Always follow safety precautions!

Carelessness on anyone's part could cause a mishap,

resulting in injuries or even deaths. By observing safety

precautions, you will reduce mishaps and save lives.

Ventilation

When you think of ventilation, you usually think of

air conditioning and cooling. However, when working

with solvents, the term

ventilation

means providing

fresh air and exhaust to the area in which you are

working. Make sure the work area is properly

ventilated. That includes topside areas of a ship because

some topside areas are enclosed on three sides and will

not allow proper ventilation.

When applying flammable coatings or using

solvents, you

must

provide adequate ventilation, which

will help prevent accidental ignition. You may have to

use extra fans or local exhaust to ventilate a space,

especially in spaces where pockets can develop. A

pocket

is the buildup of vapors and poisonous air in an

area, causing an explosion.

Always follow safety

precautions and make sure spaces are ventilated

properly when solvents are used!

When in doubt,

contact your supervisor for additional guidance.

Preventing Excess Vapors

Any type of solvent will give off some type of vapor.

These vapors may be toxic or flammable. Always use

proper ventilation to prevent a buildup of vapors. As you

have learned, some vapors can linger in pockets of

spaces; therefore, make sure the complete work area is

fully ventilated. Before starting a job, ask a gas free

engineer to examine the area for toxic gases and ask for

the proper ventilation plan for the space. Be sure to have

the space checked frequently for excessive vapors. If

vapors are found to be excessive, stop all work

immediately and have all personnel clear the area until it

is safe to return.

Protective Clothing

When working with solvents, you always face the

risk of their contacting your skin through splatters or

spills. Some caustic solvents will actually eat the skin

off your body. Make sure that you have all the protective

clothing needed for the job.

When working with solvents, you

must

wear

adequate protective clothing and gloves to prevent skin

contact with the solvents and cleaning materials.

Do not

wear jewelry or clothing with cuffs, loose pockets, rips,

or loose ties. Observe the following safety precautions

when working with solvents:

*

Wear chemical splash goggles at all times.

*

Wear acid-resistant aprons, face shield with

goggles, gloves, and boots when handling acid or

caustic cleaners.

*

Wear nonskid rubber-soled shoes when working

in enclosed spaces or when flammable vapors

may be present (spark prevention).

*

Never work in an enclosed space without using

the buddy system.

*

Respiratory protection, with either an organic

vapor cartridge or supplied air, should be worn

when dispensing, handling, or cleaning using

solvents.

Using solvents for cleaning saves time; but, make

sure you read all the labels before using the solvent.

Many solvents are corrosive and can irritate or cause

serious injuries to your eyes, skin, and lungs.

Always

check the caution labels before using any solvents!

Fire-Fighting Equipment Required While

Using Solvents

Nothing ruins a CO's day faster than receiving word

that the ship is burning. A fire can cause injury and loss

of life

and

take a ship off the line for a long time. When

working with solvents, you have no room for error. If

you're on a work detail that requires the use of solvents

18-5

Student Notes:


Page 6

or solvent-based paint, make sure the proper

fire-fighting equipment is located close to the work

area. One little spark can set the vapors of some solvents

into a roaring fire that can take life and destroy a ship.

Proper equipment may include fire extinguishers,

charged fire hoses, or foam. You always need to be

prepared. An ounce of prevention goes a long way. Ask

your supervisor to check the type of fire-fighting

equipment you are going to use to see if more equipment

or some other type is needed for the job at hand.

While working with people using solvents or

solvent-based paint, make sure you know the location of

the nearest fire alarm. Also, make sure all the people

working know the nearest fire escape route. Always

notify damage control central (DCC) when you are

using flammable materials.

Wiping Up Solvent Spills

When using solvents, be careful not to spill them on

the deck or get them on anything except what you are

cleaning. Solvents may cause paint to bubble and peel

off surfaces. The corrosive nature of some solvents can

damage equipment. When mixed with some tile

compositions, solvents can form toxic vapors that can

irritate your lungs and make you sick. If you spill

solvent, clean it up as soon as possible. If you think the

spill has caused some type of damage, contact your

supervisor for guidance.

When a spill involves more than 5 gallons of solvent

or presents a threat to the ship or the health of the crew,

report it immediately to your supervisor, DCC, or the

OOD. Each ship has a hazardous material response kit

to handle such emergencies. Spilled material and

contaminated clothing or rags become hazardous waste

and must be treated as hazardous material (HAZMAT).

Your supervisor will tell you the proper disposal

procedures for your command.

Dangers

Working with solvents is dangerous. Avoid inhaling

vapors. Personnel with a history of chronic skin disease,

allergies, or asthma should not be permitted to work

with paint, solvents, and thinners.

When you handle a solvent, don't let it contact your

skin. If a solvent does contact your skin, flush it with

clear water as soon as possible. If solvent contacts your

skin or eyes, report to the nearest medical facility as

soon as possible for treatment.

When working with solvents, wear an approved

respirator and protective clothing at all times. If you

think that your respirator isn't working properly,

request an air line mask. The safety department of your

ship usually provides these items.

If you breathe some of the vapors given off by

solvents, get to a doctor as soon as possible.

Respirators

The National Institute for Occupational Safety and

Health/Mine Safety and Health Administration

(NIOSH/MSHA) must approve all respirators and

pumps. Users must be medically qualified and fit-tested

before wearing a respirator. The following text

describes the air-purifying respirators and air-supplied

or self-contained breathing apparatus (SCBA) approved

for use by the Navy:

*

Air-purifying respirators use a filter, a chemical

cartridge, or a combination of the two to remove air

contamination. Filters capture particles of dust or metal

fumes. The cartridges may contain a chemical or carbon

to absorb vapors or gases. A combination of filter and

cartridge is used for a combination of hazards, such as

spray painting. The filter captures the spray mist and the

cartridge absorbs the paint vapors, protecting the

wearer.

*

Air-supplied or self-contained breathing

apparatus (SCBA) provides fresh air when the vapor or

gas concentration is too high or the area lacks oxygen.

Air-supplied or SCBA is required for all internal

shipboard spray painting operations. Air for supplied air

masks is provided by certified breathing air

compressors or breathing air pumps.

The use of proper equipment may save your life and

the lives of your shipmates. If you are in doubt about the

type of equipment to use, be sure to check with your

supervisor.

18-6

Student Notes:

Keep Solvent Containers Tightly Closed

Most fires in paint and solvent storage areas are

caused by a buildup of vapors. Usually, vapors escape

from containers that are not closed tightly. It only takes a

small spark to ignite these vapors. Since vapors can

quickly displace the oxygen in a storage space, there

may not be enough oxygen left to sustain life.

All containers

must

be tightly closed when not in

use. Besides the danger of vapors accumulating, air can

cause a chemical breakdown of some solvents. After a

short time, the solvent may evaporate or decay to the

point that it can't be used.

Check Containers for Leakage

The Navy uses many types of corrosive materials

that can eat through a container. You must make sure

this doesn't happen. How can you do that?

Don't accept

containers until they are inspected!

If you are

inspecting the containers, check all the seams carefully

for leaks or cracks. Check the sides of the containers for

dents. If a container is dented, that means the side of the

container may have been weakened and will eventually

leak. Don't sign for material in damaged containers. If

you are unsure of the condition of a container, ask your

supervisor to inspect it.

If you discover a leaking container while inspecting

your storage areas, find the name of the material or

solvent on the label of the container. Then immediately

inform your supervisor of the problem. The material or

solvent in the container may be caustic and highly

flammable. You and your supervisor should inspect the

damaged container and the surrounding area. Then the

material or solvent should be transferred to another

container using a standard Navy transfer pump. This

container must be equal to or surpass the storage

requirements of the damaged container.

Ensure Containers Are Empty Before

Discarding

One of the most dangerous practices is to discard

(throw away) a container partially filled with a solvent

or some type of caustic or flammable substance. For

example, several years ago a container of highly

flammable liquid was discarded into a dumpster in
