or other sources of ignition. They may explode and cause injury or death. Empty containers should be completely drained, <br />properly closed, and promptly returned to a drum reconditioner or disposed of properly. <br />rSECTION 8 EXPOSURE CONTROLS/PERSONAL PROTECTION <br />GENERAL CONSIDERATIONS: <br />Consider the potential hazards of this material (see Section 3), applicable exposure limits, job activities, and other <br />substances in the work place when designing engineering controls and selecting personal protective equipment. If <br />engineering controls or work practices are not adequate to prevent exposure to harmful levels of this material, the personal <br />protective equipment listed below is recommended. The user should read and understand all instructions and limitations <br />supplied with the equipment since protection is usually provided for a limited time or under certain circumstances. <br />ENGINEERING CONTROLS: ' <br />If user operations generate airborne material, use process enclosures, local exhaust ventilation, or other engineering <br />controls to control exposure. <br />PERSONAL PROTECTIVE EQUIPMENT: <br />Eye/Face Protection: Wear chemical goggles AND a face shield! Wear eye protection such as safety glasses, chemical <br />goggles, or faceshields if engineering controls or work practices are not adequate to prevent eye contact. <br />Skin Protection: Wear impervious protective clothing to prevent skin contact. Selection of protective clothing may include <br />gloves, apron, boots, and complete facial protection depending on operations conducted. Users should determine <br />acceptable performance characteristics of protective clothing. Consider physical requirements and other substances <br />present when selecting protective clothing. Suggested materials for protective gloves include: Neoprene, or Nitrile <br />Respiratory Protection: Wear a NIOSH approved respirator that provides protection when working with this material if <br />exposure to harmful levels of airborne material may occur, such as: Air-Purifying Respirator for Organic Vapors, Dusts <br />and Mists <br />Use a positive pressure, air-supplying respirator if there is potential for uncontrolled release, exposure levels are not <br />known, or other circumstances where air-purifying respirators may not provide adequate protection. <br />Occu ational Exposure Limits: <br />Component Limit TWA STEL Ceiling / Peak Notation <br />Disodium Carboxymethyltdthiocarbonate ACGIH Not Established NA NA NA <br />Sodium Hydroxide ACGIH Not Established NA 2 mg/m3 NA <br />Sodium Hydroxide CPCHEM 2 mg/m3 NA NA NA <br />Sodium Hydroxide German MAK 2 m /m3 NA 1 NA <br />SECTION 9 PHYSICAL AND CHEMICAL' PROPERTIES <br />APPEARANCE AND ODOR: Clear orange-red liquid with mild odor. <br />pH: NA <br />Flashpoint: 74°C (165.2°F) <br />VAPOR PRESSURE: NDA <br />VAPOR DENSITY (AIR=1): >1 <br />BOILING POINT: >100°C (212°F) <br />SOLUBILITY (in water): Completely Soluble <br />VISCOSITY: 5.44 cSt @ 21.1 °C (70°F) <br />PERCENT VOLATILE: 60 % volume <br />SPECIFIC GRAVITY: 1.3106 @ 16 °C (60°F) <br />EVAPORATION RATE: <1 <br />POUR POINT: -1°C (30.2°F) <br />SECTION 10 STABILITY AND REACTIVITY <br />Revision Number: 3 4 of 8 Orfom D8 Depressant <br />Revision Date: 09/02/2005 MSDS : 59700
