General

Your Agilent AA instrument and accessories have been carefully

designed so that when used properly you have an accurate, fast,

flexible and safe analytical system.

If the equipment is used in a manner not specified by the

manufacturer, the protection provided by the equipment may be

impaired.

Safety Practices and Hazards

8 Agilent 240/280 Series AA User’s Guide

Operation of an atomic absorption spectrometer can involve the use

of compressed gases, flames, and hazardous materials including

corrosive fluids and flammable liquids. Unskilled, improper, or

careless use of this instrument can create explosion hazards, fire

hazards, or other hazards which can cause death, serious injury to

personnel, or severe damage to equipment and property.

Information on safety practices is provided with your instrument and

operation manuals, and also referenced in your Agilent accessory

manuals. Before using your instrument or accessories, you must

thoroughly read these safety practices.

Observe all relevant safety practices at all times.

The safety practices described below are provided to help you

operate the instrument safely. Read each safety topic thoroughly

before attempting to operate the instrument and always operate the

spectrometer in accordance with these safety practices.

Electrical Hazards

The instrument and accessories contain electrical circuits, devices

and components operating at dangerous voltages. Contact with these

circuits, devices and components can cause death, serious injury, or

painful electric shock.

Panels and covers that are retained by fasteners which require the

use of a tool for removal may only be opened by Agilent field service

engineers. Consult the manuals or product labels supplied with your

PC, monitor, printer/plotter, water-cooling system and vacuum pump

(where required) to determine which parts are operator-accessible.

Application of the wrong supply voltage, connection of the

instrument to an incorrectly wired supply outlet, or lack of proper

electrical grounding can create a fire hazard or a potentially serious

shock hazard, and could seriously damage the instrument and any

attached ancillary equipment.

Always use a 3-wire outlet with ground connection which is

adequately rated for the load. The installation must comply with local

and national safety regulations.

Safety Practices and Hazards

Agilent 240/280 Series AA User’s Guide 9

Do not connect the instrument to the mains power supply until you

have made sure that the operating voltage is correctly set for the

mains power supply in the specific outlet in your laboratory to which

the equipment is connected.

Heat, Vapors and Fumes

Heat, vapors and fumes generated by flame, furnace and vapor

generation methods can be hazardous to personnel.

Heat, vapors and fumes must be extracted from the instrument by an

exhaust system. The instrument must be vented into a self-contained

arrangement of collector hood, ducting and exhaust fan. The system

must be vented to the outside air, never within the building. Locate

the system outlet such that the exhaust cannot re-enter the building

through any door, window, air conditioning inlet, or other ventilator.

Construct the system in accordance with local codes and regulations

for ventilation.

The exhaust system must be capable of providing an exhaust

ventilation rate of at least 6 cubic meters per minute (200 cfm).

Locate the exhaust fan at least 3 meters (10 feet) away from the

flame and as close to the outlet as possible. The motor must be

mounted away from the hot gases, and plastic parts must not be used

as they will melt. Fit a back-draft damper to the outlet end of the

system. Equip the exhaust fan power supply with an indicator close

to the instrument to indicate whether the exhaust fan is on or off.

Always switch the exhaust fan on before lighting the flame.

Use fireproof ducting that is in accordance with your local fire

prevention regulations. Locate the ducting away from fire alarms,

sprinkler heads and other heat-sensitive devices. Do not make solder

joints in the ducting—the hot exhaust in the duct may melt the joint.

Regularly check the system by smoke test to ensure that the exhaust

system is working.

When operating the atomic absorption spectrometer, always have the

chimney in place to ensure correct ventilation.

Safety Practices and Hazards

10 Agilent 240/280 Series AA User’s Guide

Compressed Gases and Cylinders

All compressed gases (other than air) can create a hazard if they leak

into the atmosphere. Even small leaks in gas supply systems can be

dangerous. Any leak (except that of air) can an explosion hazard, a

fire hazard, or result in an oxygen–deficient atmosphere. Such

hazards can cause death, serious injury, asphyxiation, anesthetic

effects, and serious damage to equipment and property.

Cylinders must be stored and handled strictly in accordance with

local safety codes and regulations. Cylinders must be used and stored

only in a vertical position. Secure all cylinders to an immovable

structure or a properly constructed cylinder stand. The area in which

cylinders are stored must be adequately ventilated to prevent toxic or

explosive accumulations. Move cylinders only on a properly

constructed trolley.

Keep cylinders cool. This rule applies to every cylinder of

compressed gas. Cylinders have pressure relief devices that release

the contents of the cylinder if the temperature exceeds 52 °C

(125 °F).

Ensure that all cylinders are clearly labeled so that there can be no

doubt about the contents. If the cylinder label is not legible, do not

use the cylinder—return it to your supplier. Always ensure that you

have the right cylinder before connecting the cylinder to the

instrument.

If air is supplied from a compressor, all moisture must be extracted

from the air before it is supplied to the gas control module. Moisture

can affect the internal components of the gas control system and

create a potentially hazardous situation.

Use only approved regulators and hose connectors.

Never attempt to refill cylinders.

Remember that for cylinder connections, left-hand thread fittings are

used for fuel; right-hand thread fittings are used for support gases.

When your analytical program is complete, or at the end of the

working day, always ensure that all gas supplies are turned off at the

cylinders.
