 0 = &lt;span class=&quot;abbr&quot; style=&quot;color: black;&quot; title=&quot;Flammability 0.  Will not burn. (e.g., water)&quot;&gt;0&lt;/span&gt; |
 1 = &lt;span class=&quot;abbr&quot; style=&quot;color: black;&quot; title=&quot;Flammability 1.  Must be pre-heated before ignition can occur. (e.g., canola oil) Flash point over 93°C (200°F).&quot;&gt;1&lt;/span&gt; | 
 2 = &lt;span class=&quot;abbr&quot; style=&quot;color: black;&quot; title=&quot;Flammability 2.  Must be moderately heated or exposed to relatively high ambient temperature before ignition can occur. (e.g. diesel fuel) Flash point between 38°C (100°F) and 93°C (200°F).&quot;&gt;2&lt;/span&gt; |
 3 = &lt;span class=&quot;abbr&quot; style=&quot;color: black;&quot; title=&quot;Flammability 3.  Liquids and solids that can be ignited under almost all ambient temperature conditions. (e.g., gasoline) Flash point below 38°C (100°F) but above 23°C (73°F).&quot;&gt;3&lt;/span&gt; |
 4 = &lt;span class=&quot;abbr&quot; style=&quot;color: black;&quot; title=&quot;Flammability 4.  Will rapidly or completely vaporize at normal atmospheric pressure and temperature, or is readily dispersed in air and will burn readily. (e.g., propane) Flash point below 23°C (73°F).&quot;&gt;4&lt;/span&gt; |

 0 = &lt;span class=&quot;abbr&quot; style=&quot;color: black;&quot; title=&quot;Health 0.  Exposure under fire conditions would offer no hazard beyond that of ordinary combustible material. (e.g., sodium chloride)&quot;&gt;0&lt;/span&gt; |
 1 = &lt;span class=&quot;abbr&quot; style=&quot;color: black;&quot; title=&quot;Health 1.  Exposure would cause irritation but only minor residual injury. (e.g., turpentine)&quot;&gt;1&lt;/span&gt; | 
 2 = &lt;span class=&quot;abbr&quot; style=&quot;color: black;&quot; title=&quot;Health 2.  Intense or continued but not chronic exposure could cause temporary incapacitation or possible residual injury. (e.g., chloroform)&quot;&gt;2&lt;/span&gt; |
 3 = &lt;span class=&quot;abbr&quot; style=&quot;color: black;&quot; title=&quot;Health 3.  Short exposure could cause serious temporary or residual injury. (e.g., chlorine gas)&quot;&gt;3&lt;/span&gt; |
 4 = &lt;span class=&quot;abbr&quot; style=&quot;color: black;&quot; title=&quot;Health 4.  Very short exposure could cause death or major residual injury. (e.g., VX gas)&quot;&gt;4&lt;/span&gt; |

 0 = &lt;span class=&quot;abbr&quot; style=&quot;color: black;&quot; title=&quot;Reactivity 0.  Normally stable, even under fire exposure conditions, and is not reactive with water. (e.g., liquid nitrogen)&quot;&gt;0&lt;/span&gt; |
 1 = &lt;span class=&quot;abbr&quot; style=&quot;color: black;&quot; title=&quot;Reactivity 1.  Normally stable, but can become unstable at elevated temperatures and pressures. (e.g., calcium)&quot;&gt;1&lt;/span&gt; | 
 2 = &lt;span class=&quot;abbr&quot; style=&quot;color: black;&quot; title=&quot;Reactivity 2.  Undergoes violent chemical change at elevated temperatures and pressures, reacts violently with water, or may form explosive mixtures with water. (e.g., phosphorus)&quot;&gt;2&lt;/span&gt; |
 3 = &lt;span class=&quot;abbr&quot; style=&quot;color: black;&quot; title=&quot;Reactivity 3.  Capable of detonation or explosive decomposition but requires a strong initiating source, must be heated under confinement before initiation, reacts explosively with water, or will detonate if severely shocked. (e.g., fluorine)&quot;&gt;3&lt;/span&gt; |
 4 = &lt;span class=&quot;abbr&quot; style=&quot;color: black;&quot; title=&quot;Reactivity 4.  Readily capable of detonation or explosive decomposition at normal temperatures and pressures. (e.g., Nitroglycerin)&quot;&gt;4&lt;/span&gt; |
