Safety instructions
1.9 Handling solvents
Takethefollowingprecautionswhenhandlingcleaningsolventsduringsolderprintingorpreparation.
Hazards when handling solvents
1. Hazards to human health
Organicsolventsconstantlyvaporizeandcontaminatethesurroundingatmosphere.Inhalingorcomingincontactwith
organicsolventvapormaycauseseriousdamagetohumanhealth.
2. Flammability
Organicsolventsarehighlyflammablesubstancesandcaneasilycatchfireifhandledimproperly.
3. Adverse effects on machines
Somesolventtypeswilldamagethecleaningunit,electricalwiresheathandvariousunitsusedinthesolderpaste
printer.
To avoid hazards of solvents
1.Becarefulnottoinhaletoxicvaporsofsolventsforextendedperiods.
2.Donotusesolventsnearfireorflame.Keepsolventsawayfromflameorfire.
3.Useonlythespecifiedsolventinthecorrectmanner.Donotreuseanysolventrepeatedly,anddonotmixwithother
solventsorchemicals.
1.10 Handling the X-ray unit
SomeYSseriesinspectionequipmentmodelscontainanX-rayunit.Takethefollowingprecautionswhenusing
withanX-rayunit.
1. The X-ray output window of the X-ray source is made of very thin beryllium foil.
· Berylliumintheformofdustparticlescancauseacutetoxicityorchronictoxicity,andmayinducerespiratory
problemsifinhaled.
· Toensuresafety,theX-rayunitisdesignedsothattheX-raywindowcannotbetouched.However,shouldtheX-ray
outputwindowbebrokenforsomereason,immediatelyturnoffthepowerswitchanduseextremecarenottoinhale
thedustparticles.
· ChlorinegascancorrodetheberylliumwindowoftheX-raytube,causingpermanentdamagetotheX-raytube.Do
notusetheX-rayunitinenvironmentswherechlorinegasesaregenerated.Takespecialcarewhenhandlingsamples
suchasvinylchloridematerialswhichmaygeneratechlorinegases.
2. Lead is used in the covers of machines equipped with an X-ray unit.
Althoughleadissealedwithinthecoverssothattheleadportionscannotbedirectlytouched,usecautionsinceleadis
knownasheavymetalhavingharmfuleffects.
3. A safety key is provided for machines equipped with an X-ray unit.
Thesafetykeymustbemanagedbythesupervisorofthemachine.
4. Safety education about X-ray
AppropriatemeasuresaretakenforYAMAHA'sX-rayunitsothattheamountoftheX-rayleaktotheoutsideofthe
equipmentisverysmall.Therefore,whenusingthisequipmentinJapan,itisnotnecessarytosetcontrolledareasdefined
inArticle3oftheOrdinanceonPreventionofIonizingRadiationHazards.
Itisnotlegallyobligatedtoconductthesafetyeducation,butitisrecommendedtoconducttheeducationbythe
customer.
WhenoperatingthisequipmentoutsideJapan,thesafetyeducationisconductedasrequiredaccordingtotherelevant
country'slaws,regulations,andstandards.
TIP
When conducting the safety education in Japan, the contents stated in “Special Education Standard for Radiography
(Ordinance of the Ministry of Health, Labor and Welfare No. 50)” are recommended. However, the safety education
does not necessarily need to be these contents.
