SECTION 11: Toxicological information Information on toxicological effects Other toxicological data No reason for classification as acute toxiska. Toxicological data for substances

10 Heydi Trollkraft - Version 4 Page 10 of 20 Substance Acute toxicity Calcium Oxide Type of toxicity: Acute Effect tested: LD50 Route of exposure: Oral Value: > 2000 mg/kg Animal test species: rat Test reference: OECD 425 Type of toxicity: Acute Effect tested: LD50 Route of exposure: Dermal Value: > 2500 mg/kg Animal test species: rabbit Test reference: OECD 402 Inhalation Skin contact Eye contact Ingestion Skin corrosion / irritation Serious eye damage / irritation Respiratory or skin sensitisation Mutagenicity Reproductive toxicity STOT-single exposure STOT-repeated exposure Aspiration hazard Substance Irritating to respiratory system. Irritating to skin. Calcium oxide entails a risk of serious damage to the eye (eye irritation studies (in vivo, rabbit). Based on Experiment results, calsium oxide requires classification as severely irritating to the eyd Eye Damage 1 (H318 - Causes erious eye demage). Corrosive effect on the lining of the mouth, throat and stomach, causing severe pain. Calcium oxide is irritating to the skin (in vivo, rabbits). Based on experimental results, Calcium oxide requires classification as irritating to skin Skin Irrit 2 (H315 - Causes skin irritating). Calcium oxid entails a risk of serious damage to the eye (eye irritation studies (in vivo, rabbit=. Based on experimental results, Calcium oxide requires classification as severely irritating to the eye Eye Damage 1 (H318 - Cause serious eye damage). No data available. Calcium oxide is considered not to be a skin sensitiser, based on the nature of the effect (ph shift) and the esssential requirement of Calcium for human nutrition. Classification for sensitisation is not warranted. Human epidemiological data indicate that calcium deficiencies potential for reproduction. By reason of the ph effect is not indicative of a reproductive risk. Calcium oxide is classified as irritating to the respiratory system. STOT SE 3 (H335 - kan irritere luftveiene), Toxicity of Calcium via the oral route is addressed by upper intake Levels (UL) for adults determined by the Scientific Committee on Food (SCF), being UL=2500 mg/ d, corresponding to 36 mg/kg bw/d (70 kg person) for Calcium. Toxicity of CaO via inhalation (local effect, irritating of mucous membranes) is addressed by an 8-h TWA determined by the Scientific Committee on Occupational Exposure Limits (SCOEL) of 1 mg/m³ respirable dust (see 8.1) Therefore, classification of CaO for toxicity upon prolonged exposure is not rexquired. Calcium oxide is not known to present an aspiration hazard. Aluminous cement

11 Heydi Trollkraft - Version 4 Page 11 of 20 Skin corrosion / irritation Serious eye damage / irritation Respiratory or skin sensitisation Substance Acute toxicity No irritant effect. (OECD 404) No irritating. (OECD 405) Does not contain measurable amounts of soluble Chromium VI. Sodium polynaphtylmethane sulphonate Type of toxicity: Acute Effect tested: LD50 Route of exposure: Oral Value: ~ 3000 mg/kg Animal test species: rat Comments: Literature information Acute toxicity, Mixture estimate Distribution Metabolism Toxicokinetics Not known. Not known. Not known. Potential acute effects Inhalation Skin contact Eye contact Ingestion Dust in high concentrations may irritate the respiratory system. The product is dust reduced. The risk of exposure to respirable dust is therefore greatly reduced. From the experimental results (rabbit) is potassium oxide is klassifisert as Irritant to skin R38 Irritating to skin; Skin Irrit 2 (H315 - Causes skin irritation). From the experimental results (rabbit) is calcium oxide is classified as highly irritating to eyes, Eye Demage 1 (H318. Causes serious eye damage). Do not use contact lenses. Wear tight fitting safety glasses with side shields or full goggles with wide field of view. It is also advisable to have a personal pocket eyewash. Corrosive effect on the lining of the mouth, throat and stomach, causing severe pain. Delayed effects / repeated exposure Sensitisation Chronic effects Calcium will not cause skin allergy from its effect in nature (ph change) and because calcium is an essential element for human nutrition. No basis for classification as a sensitiser. Risk of long-term effects is expected to be minimal from occupational exposure. Carcinogenic, Mutagenic or Reprotoxic Carcinogenicity, other information Mutagenicity Teratogenic properties Calcium (Ca-Lactate solution) is not carcinogenic (results from experiments on rats). ph effect of calcium is not a risk to cause cancer. Epidemiological data from humans do not indicate that calcium has no ability to cause cancer. No basis for classification as a carcinogen. Not known. Calcium (Ca carbonate) is not toxic for reproduction (results from experiments on

12 Heydi Trollkraft - Version 4 Page 12 of 20 mice). ph effect does not mean no risk of spreading. Epidemiological data from humans show that calcium deficiencies potential for reproductive toxicity. Neither animal studies or clinical trials on people with different calcium salts has shown some effects on reproduction or fetal development. Calcium oxide is not toxic for reproduction or fetal development. It does not require classification as a reproductive toxin under Regulation (EC) 1272/2008. Reproductive toxicity None known Symptoms of exposure Symptoms of overexposure The oral toxicity of the calcium taken care of by the upper intake limit (UL) for adults in the EU's Scientific Committee for Food (SCF) is designed for UL = 2500 mg / dog reacts to 36 mg / kg bw / d (70-kg person ) for calcium. The toxicity of CaO through the skin is not considered relevant because of the expected negligible absorption through the skin and that local irritation is the main health effect (ph change). The toxicity of CaO by inhalation (local effect, mucous membrane) is handled by an 8-hour TWA as the EU Scientific Committee for Occupational Exposure Limits (SCOEL) has been set at 1 mg / m³ respirerbart dust (see Section 8.1). Therefore, there is no reason to classify CaO as toxic with prolonged exposure. SECTION 12: Ecological information Toxicity Ecotoxicity Calcium oxide in high concentration is used desinfeksjon of sewage sludge because the temperature and increasing ph. Addition of the product in water will increase the ph of the water and therefore have some toxic effect on aquatic life under certain conditions.

Exposure Scenario 1.1 Contributing scenario controlling environmental exposure Name of contributing scenario Further explanation PROC 19 Unngå innånding eller svelging. Generelle yrkesmessige hygienetiltak er nødvendig for å sikre trygg håndtering av stoffet. Disse tiltakene involverer god personlig og generell ryddighet (dvs. regelmessig rengjøring med egnede rengjøringsenheter), ingen bespising og røyking på arbeidsplassen, bruk av standard arbeidsklær og sko hvis ikke annet er angitt under. Dusj og skift klær når arbeidsskiftet er ferdig. Ikke bruk tilsølte klær hjemme. Ikke blås av støv med trykkluft. Section 2 Field for additional explanations of scenario if required. Eksponeringsestimerings-verktøyet MEASE ble brukt til å vurdere innåndingseksponeringen. Risikokarakteristikkforholdet (RCR) er kvotienten til det raffinerte eksponeringsestimatet og respektive DNEL (utledet "ingen effekt"-nivå) og må være under 1 for å utvise sikker bruk. For innåndingseksponering er RCR basert på DNEL for CaO til 1 mg/m³ (som respirabelt støv) og det respektive innåndingseksponerings-estimatet som er utledet ved bruk av MEASE (som inhalerbart støv). Derfor har RCR en ekstra sikkerhetsmargin siden den respirable fraksjonen er en underfraksjon av den innåndingsbare fraksjonen iht. EN 481. Section 2.1 Product properties Physical form (phase) of product Sprengsement for oppsprekking og deling av stein, fjell og betong. Pulver

Avhengig av diameter og dybde. Blanding og fylling ca. 5 min. Benytt vernehansker/verneklær/vernebriller/ansiktsskjerm. For å unngå helseskade skal "gjør-det-selv"-er være i samsvar med de samme strenge vernetiltakene som gjelder for profesjonelle arbeidsplasser:? Bytt tilsølte klær, sko og hansker umiddelbart.? Beskytt utildekkede hudområder (armer, legger, ansikt): Det finnes forskjellige effektive hudbeskyttelsesprodukter som bør brukes i henhold til en hudbeskyttelsesplan (hudbeskyttelse, rensing og pleie). Rens tilsølt hud grundig etter arbeidet og påfør et pleieprodukt. For å unngå helseskade skal "gjør-det-selv"-er være i samsvar med de samme strenge vernetiltakene som gjelder for profesjonelle arbeidsplasser:? Ved klargjøring eller blanding av bygningsmaterialer, rivingsarbeid eller fuging (kalfatring), og fremfor alt under arbeid over hodehøyde, skal man bruke vernebriller og ansiktsmasker under støvete arbeid.? Vær nøye ved valg av arbeidshansker. Skinnhansker blir våte og gi lettere brannsår. Når man arbeider i et vått miljø, er bomullshansker med plastbelegg (nitril) bedre. Bruk mansjetthansker ved arbeid over hodehøyde fordi de kan re-dusere fuktigheten som trenger inn i arbeidsklærne betydelig. Section 2.2 Product properties Operating conditions Spesialsement som etter utblanding med vann, utvikler et enormt ekspansjonstrykk - opptil 9000 tonn/m² - som bevirker lydløs og sikker oppsprekking og demolering av fjell og betong. Ikke relevant. Risk Management Measures Conditions and measures related to personal protection, hygiene and health evaluation Unngå søl og kontakt med huden og øynene. Unngå å bruke kontaktlinser når du håndterer dette produktet. Førstehjelpsutstyr inkl. øyeskylleflaske skal være tilgjengelige på arbeidsplassen. Produktet er støvredusert, men fortsatt unngå støvdannende håndtering. Følg bruksanvisningen. Section Health Measured data has been used to estimate worker exposure Risikokarakteristikkforholdet (RCR) er kvotienten til det raffinerte eksponeringsestimatet og respektive DNEL (utledet "ingen effekt"-nivå) og er oppgitt i parentes under. For innåndingseksponering er RCR basert på den akutte DNEL for kalkstoffer til 4 mg/m³ (som respirabelt støv) og det respektive innåndingseksponerings-estimatet (som inhalerbart støv). Derfor har RCR en ekstra sikkerhetsmargin siden den respirable fraksjonen er en underfraksjon av den innåndingsbare fraksjonen iht. EN 481. Siden kalk er klassifisert som irriterende for hud og øyne, er det foretatt en kvalitetsmessig vurdering for dermal eksponering og eksponering til øyet. Section 4

18 Heydi Trollkraft - Version 4 Page 18 of Health Guidance to DU (downstream user) Produktet inneholder kalsiumoksid som blandet med vann virker aggressivt på hud og på slimhinner i øyne, nese og svelg. Les alltid advarselstekst på pakningen før arbeid igangsettes. Svelging - Kvalitetsmessig vurdering Oral eksponering oppstår ikke som del av tiltenkt bruk av produktet. Dermal - Liten oppgave: 0,1 µg/cm² (-) Stor oppgave: 1 µg/cm² (-). Kvalitetsmessig vurdering Hvis man tar risikoreduksjonstiltak i betraktning, forventes det ingen eksponering for mennesker. Dermal kontakt overfor støv fra lasting av kalkstoffer eller direkte kontakt med kalk kan imidlertid ikke utelukkes hvis det ikke blir brukt beskyttelseshansker under påføringen. Dette kan av og til føre til mild irritasjon som er enkelt å unngå ved å umiddelbar skylling med vann. Mengdevurdering Den konstante mengdemodellen til ConsExpo er blitt brukt. Kon-taktrate til støv som dannes mens det tømmes pulver er tatt fra "gjør-det-selv"1-faktaarket (RIVM rapport ). Øyne - Støv Kvalitetsmessig vurdering Hvis man tar risikoreduksjonstiltak i betraktning, forventes det ingen eksponering for mennesker. Støv fra lasting av kalkstoffene kan ikke utelukkes hvis det ikke blir brukt beskyttelsesbriller. Umiddelbar skylling med vann anbefales, og oppsøk lege etter eksponering ved et uhell. Inhalering - Liten oppgave: 12 μg/m³ (0,003) Stor oppgave: 120 μg/m³ (0,03) 4.2. Environment Environment Akutt ph-virkning. Dette produktet er nyttig for å korrigere surheten i vann, men konsentrasjoner på over 1 g/l kan være skadelig for livet i vannet. En ph-verdi over >12 vil imidlertid synke raskt på grunn av fortynning og karbonatisering. I henhold til OC/RMM-er knyttet til miljøet skal man unngå utslpp av kalkoppløsninger direkte i kommunalt avløpsvann. ph-verdien til et kommunalt kloakkbehandlingsanlegg miljønøytralt, og derfor forekommer det ingen eksponering til den biologiske aktiviteten. Det som strømmer inn i et kommunalt kloakkbehandlingsanlegg nøytraliseres ofte på en eller annen måte, og kalk kan også brukes på en fordelaktig måte for ph-styring av sure avløpsvannsstrømmer som behandles i biologiske WWTP-er. Siden ph-verdien til det som strømmer inn i det kommunale behandlingsanlegget er miljønøytralt, er ph-innvirkningen ubetydelig på de mottakende miljørommene, som f.eks. overflatevann-, sediment- og grunnmur/kjellere.

Risikokarakteristikkforholdet (RCR) er kvotienten til det raffinerte eksponeringsestimatet og respektive DNEL (utledet "ingen effekt"-nivå) og må være under 1 for å utvise sikker bruk. For innåndingseksponering er RCR basert på DNEL for CaO til 1 mg/m³ (som respirabelt støv) og det respektive innåndingseksponerings-estimatet som er utledet ved bruk av MEASE (som inhalerbart støv). Derfor har RCR en ekstra sikkerhetsmargin siden den respirable fraksjonen er en underfraksjon av den innåndingsbare fraksjonen iht. EN 481. Section 2.1 Product properties Physical form (phase) of product Concentration of substance in product Amount used Frequency and duration of use Human factors not influenced by risk management CS 135: General Measures applicable to all activities Sprengsement for oppsprekking og deling av stein, fjell og betong. Pulver 60-80% Vanskelig å oppgi. Avhengig av diameter og dybde. Blanding og fylling ca. 5 min. Skift i pustevolum under alle prosesstrinn gjenspeilet i PROC-ene antas å være 10 m³/skift (8 timer). Benytt vernehansker/verneklær/vernebriller/ansiktsskjerm. Siden Ca(OH)2 er klassifisert som irriterende for huden, er det obligatorisk å bruke beskyttelseshansker for alle prosesstrinn. Øyebeskyttelsesutstyr (f.eks. briller eller visir) må brukes, med mindre potensiell kontakt med øynene kan utelukkes av naturlige årsaker og type bruk (f.eks. lukket prosess). I tillegg må ansiktsbeskyttelse, vernetøy og vernesko brukes ved behov. Section 2.2 Product properties Spesialsement som etter utblanding med vann, utvikler et enormt ekspansjonstrykk - opptil 9000 tonn/m² - som bevirker lydløs og sikker oppsprekking og demolering av fjell og betong.

Metode brukt for vurdering av innåndingseksponering - MEASE. Estimat for innåndingseksponering (RCR) - < 1 mg/m³ (0,5 0,825) Siden Ca(OH)2 er klassifisert som irriteren-de for huden, må dermal eksponering minimeres som langt det er teknisk mulig. En DNEL for dermale effekter er ikke utledet. Derfor vurderes ikke dermal eksponering i dette eksponeringsscenariet. Section Environment Environment For all annen bruk utføres det ingen kvantitativ miljøeksponeringsvurdering fordi? Driftsforhold og risikostyringstiltak er mindre bindende enn de som er angitt for beskyttelse av jordsmonnet i landbruket eller for behandling av jordsmonnet innen bygg og anlegg.? Kalk er en ingredisens og kjemisk bundet i en matrise. Utslipp er neglisjerbart og ikke tilstrekkelig til å forårsake en endring i ph i jordsmonnet, avløpsvann eller overflatevann? Kalk brukes spesifikt til å frigjøre CO2-fri pusteluft gjennom at det reagerer med CO2. Slike anvendelser er kun relevante for luftrom hvor egenskapene til kalk nyttiggjøres? Nøytralisering/pH-skift er tiltenkt bruk og har ingen effekter ut over det som er tilsiktet. Section 5
