Avoid dust formation. Refer to protective measures listed in Sections 8 and 13. SECTION 7. HANDLING AND STORAGE Handling Wear personal protective equipment/face protection. Ensure adequate ventilation. Avoid contact with skin, eyes or clothing. Avoid ingestion and inhalation. Avoid dust formation. Storage Store under an inert atmosphere. Keep container tightly closed in a dry and well-ventilated place. Air sensitive. Specific Use(s) Use in laboratories SECTION 8. EXPOSURE CONTROLS/PERSONAL PROTECTION Control Parameters Monitoring methods BS EN 14042:2003 Title Identifier: Workplace atmospheres. Guide for the application and use of procedures for the assessment of exposure to chemical and biological agents. MDHS14/3 General methods for sampling and gravimetric analysis of respirable and inhalable dust MDHS 91 Metals and metalloids in workplace air by X-ray fluorescence spectrometry MDHS 99 Metals in air by ICP-AES Exposure Controls Engineering Measures Ensure adequate ventilation, especially in confined areas. Wherever possible, engineering control measures such as the isolation or enclosure of the process, the introduction of process or equipment changes to minimise release or contact, and the use of properly designed ventilation systems, should be adopted to control hazardous materials at source. Personal protective equipment Eye Protection Wear safety glasses with side shields (or goggles) (European standard - EN 166) Hand Protection Protective gloves Glove material Breakthrough time Glove thickness EU standard Glove comments Nitrile rubber See manufacturers - EN 374 (minimum requirement) recommendations Inspect gloves before use. Please observe the instructions regarding permeability and breakthrough time which are provided by the supplier of the gloves. (Refer to manufacturer/supplier for information) Ensure gloves are suitable for the task: Chemical compatability, Dexterity, Operational conditions, User susceptibility, e.g. sensitisation effects, also take into consideration the specific local conditions under which the product is used, such as the danger of cuts, abrasion. Remove gloves with care avoiding skin contamination. Skin and body protection Long sleeved clothing Respiratory Protection When workers are facing concentrations above the exposure limit they must use appropriate certified respirators. To protect the wearer, respiratory protective equipment must be the correct fit and be used and maintained properly Large scale/emergency use In case of insufficient ventilation, wear suitable respiratory equipment ______________________________________________________________________________________________ Page 3 ``` ## Page 4 ```text ALFAA42878 SAFETY DATA SHEET Revision Date 30-Jul-2026Page 4 / 7 Europium(III) acetate hydrate, REacton® ______________________________________________________________________________________________ Recommended Filter type: Particle filter Small scale/Laboratory use Use a NIOSH/MSHA or European Standard EN 149:2001 approved respirator if exposure limits are exceeded or if irritation or other symptoms are experienced.
