• full-body coverall (chemical coverall) or chemical protective suit

• sturdy shoes or acid-resistant boots

• closed protective glasses or visor with full mask

• helmet or helmet with neck guard

• acid-resistant protective gloves

The specific protective clothing and equipment to be used must be stipulated in substance-related and workplace-related company rules.

Vehicle drivers must carry the protective equipment readily available in the vehicle. This alsoapplies to the transport of empty tanks which have not yet been cleaned.

7.1.1 Equipment for the loading and unloading stations

Take precautions to prevent the movement of the tanker during the loading and unloadingoperations.Restrict entry to the loading area to that required to follow the work instructions.

7.1.2 Working platform


4/10

The working platform of the loading station should have folding steps and the followingequipment should be installed on the working platform

• the filling arm or arms .

• devices for leak detection testing

• flushing water connection

• safety equipment such as eye shower and emergency shower

• emergency switch to stop the loading operation

7.1.3 illing arm

The filling arm must be made from a suitable material and the following equipment must beattached

• a shut-off valve

• a connection to an e!tractor or gas displacement line

• a safeguard against overfilling

• a drip collector

7.1.! "oading area

The loading and unloading areas should be built in such a way that leaks" spillage and overflowis collected and led to a safe place.

7.2.2 #uita$ility of the tanks

#nsure that

9he tan? has been approved or nitric acid use:

9he related approval o the tan? use must be chec?ed be ore a tan? may be illed. 5ocalprocedures are re3uired to ensure that such an approval e)ists.

• The tank equipment is suitable for nitric acid

The hose material and the couplings used for unloading must not react with nitricacid (for e!ample" bron$e couplings are unsuitable).

• The tank and equipment are undamaged

'o not use damaged tanks for transporting nitric acid. heck visually before fillingto ensure that the tank is free from mechanical damage" such as dents or cracks. 'onot fill the tank if any obvious defects are found at the loading point.

The tank equipment may also have defects in addition to mechanical damage to thetank. ay special attention to the seals during filling. &ll the seals must be present"

Replace any missing items of equipment before transportation. This appliesparticularly to nuts" bolts and securing pins etc." in the case of tank wagons.

11.2 hecklists

The emptying of tanks should be documented using checklists. The sample checklists in&nne!es * and + may be used after deleting the points which relate e!clusively to loading. Thesample checklists may need the addition of plant-related points.

The obligations specified in the checklists are described in the following sections.

0nspections $efore emptying tanks

%efore emptying tanks ensure

• the tank contains the desired product (in particular that it is the correct tank chamberto be emptied).

• emptying takes place using only materials" seals" equipment and protective liningswhich have no dangerous reactions with nitric acid or which produce dangerousproducts or are substantially weakened by the dangerous products.

• #l tanque de recibo tiene capacidad para recibir el volumen en carrotanque.

11. (ightness of emptied tanks

#mpty tanks which have not been cleaned must be sealed as tightly as full tanks.

ay attention to the handling of empty tanks and in particular to -

• preventing the release of dangerous quantities of gases and vapours and taking thenecessary action (e.g. gas displacement" e!traction).

• closing the shut-off devices located nearest to the product first. This will preventproduct from accumulating between the bottom valve and the discharge valve.

• relieving the pressure in the tank after pressurised emptying.

• clearing product from the tank pipes and hoses used for emptying before continuing thetransport run.

witch off the engine of the vehicle if it is not required for operating pumps or otherequipment for emptying the vehicle.

#nsure that connection elements to emptying devices comply with the same safetyrequirements as the means of transport. #nsure that the filling and emptying pipes not locatedpermanently on the vehicle tank are empty after emptying the tank and during transit.

Remove any contamination or ha$ardous residues adhering to the outside of the empty tanksbefore transit.

38. Electricidad Estática

a 5os hidrocarburos pueden car$arse con electricidad est4tica con el bombeo1 llenado de a$ua1o por colocar a$ua dentro de ellos. 5as tasas de lu0o de alta velocidad aumentan la$eneraci!n de est4tica la cual puede dar como resultado una chispa en la super icie.

b Un tasa ba0a de lu0o ayuda a no producir y a disipar r4pidamente una car$a est4tica.

c Cuando se vierten luidos no conductores desde un contenedor a un recipiente1 entonces el

contenedor1 el recipiente y el embudo1 Si se usa1 deben ser conectados 0untos y a tierra.9odos los e3uipos deben ser met4licos. 5a vasi0as receptoras y las bo3uillas de car$a oman$ueras deber4n conectarse a tierra durante las operaciones de trans erencia.

d Cuando sea practico1 se deben mantener mantas de $as inerte sobre el li3uido en elalmacenamiento cuando se reali6an operaciones de iltraci!n.

e Otros elementos de uso com(n los cuales pueden ocasionar la $eneraci!n de electricidadest4tica sino se Aterri6an apropiadamente son: ma3uinas de vapor1 ma3uinas de a$ua dealta presi!n1 ventiladores1 chorro de arena e incluso inos aerosoles de a$ua usados enactividades contra incendio.

Buardas deben incluir bo3uillas de cone)i!n y el uso de man$ueras anti est4tica Estas ultimasse deben marcar a intervalos de tres metros.

39. Conexiones a Tierra

Llenado o Descargue de Carro-tanques

Se deben hacer cone)iones de empalme durante el car$ue o descar$ue de carrotan3uescuando los l23uidos tienen un punto de i$nici!n de ,++ $rados $rados Cent2$rados oin erior y cuando puede haber presencia de vapores de estos l23uidos en el tan3ue.

Se deben hacer cone)iones de empalme cuando est4 abierta la tapa del tan3ue y se debende0ar hasta cuando se cierre y se ase$ure la tapa despu8s de terminar de car$ar odescar$ar.

El empalme deber4 hacerse con cable met4lico de empalme conectado permanentemente aal$una clase de estructura 3ue est8 en contacto con el tan3ue 3ue se car$a o descar$a.

El e)tremo libre del cable debe tener un $ancho o dispositivo similar para conectarlocorrectamente.

5os cables de empalme pueden sea aislados o sin aislamiento.

El aislamiento de los cables se debe probar anualmente. 5as pruebas deber4n incluir todo elcircuito de empalme1 y deber4n estar documentadas
