SAFETY DATA SHEET

• H001: Causes partial shadow. Not full shadow. Partial. We cannot stress this enough.
• H002: May cause the sun to appear as a bright crescent, ring, or irregular arc depending on eclipse geometry. Legal has reviewed this framing and confirmed it is a feature, not a defect.
• H003: Extended exposure may induce philosophical uncertainty about the nature of "enough."
• H004: Reduces solar panel output by 15–80% depending on coverage geometry. Homeowners' insurance implications remain unresolved. See Sections 9 and 15.
• H005: Product contains trace amounts of hope for totality. Hope is not totality. Users should not confuse these at any point before, during, or after the event.

• P001: Do not look directly at source. Eclipse glasses required even though you will be underwhelmed.
• P002: Keep eclipse chasers who drove more than 8 hours away from product if at all possible. Eclipse chasers are a sensitive population. Their sensitivity is not our liability.
• P003: If disappointment occurs, do not attempt to reposition the moon yourself. No one has done this successfully.
• P004: Store expectations in a sealed container prior to deployment. Expectations left unsealed before the event will not be covered under any warranty.

This product intentionally contains NO complete darkness. This is not an impurity. This is the product. The product is working correctly.

Eye Contact: If exposed to penumbra while expecting totality, lower eclipse glasses slowly. The sun is still there. It has always been there. Rinse eyes with acceptance. Seek information on the next total solar eclipse — specific path, specific date, do not arrive in the penumbra zone again. Begin planning now. Get the passport.

If You Drove More Than 8 Hours For This: Do not call Poison Control. Poison Control has asked us specifically to include this. They cannot help you. Contact the tour operator. Review the refund policy. Note that weather and orbital geometry are, per the fine print, excluded causes.

Emotional Exposure: Sit quietly. The penumbra is doing its best. The penumbra is a natural shadow produced by partial solar occlusion and it did not make you drive to rural Idaho. That was a choice you made. The penumbra was not consulted.

When to Seek Medical Attention: If the feeling "it's still pretty cool, actually" fails to develop within 20 minutes of exposure, consult a physician or lower your expectations. Both are clinically recognized interventions for this presentation.

PENUMBRA-7™ is not flammable. It is a shadow. Attempting to extinguish it with water, foam, CO₂, or dry chemical agents will have no effect on the shadow and will get you wet or covered in powder. If a fire occurs within the penumbra zone, fight it normally. The penumbra will not assist or obstruct. It will simply be there, partially.

Hazardous Combustion Products: None attributable to this product. Any combustion hazards in the penumbra zone are the responsibility of the party who created them, which is not us. We are a shadow.

Special Protective Equipment for Firefighters: Standard gear. Eclipse glasses are specifically NOT required or recommended during a fire response. This is noted here because someone asked.

PENUMBRA-7™ will appear whether or not it is desired. It cannot be contained. It cannot be diverted. It travels at approximately 1,000 mph across the Earth's surface and does not require a permit for this.

Accidental releases occur during all partial solar eclipses, transits of Mercury and Venus, and — in a technical sense — any time a cloud covers 15–99% of the sun. Liability for cloud-induced penumbral states is under ongoing legal review. See Estate of Hawkins v. Cumulus Formation LLC, unreported, 2021, currently on appeal.

Personal Precautions: Do not stand in the penumbra expecting it to become the umbra. This is the most common misuse scenario documented in our incident reports. You were given a map. The path of totality was clearly delineated on the map. The map was accurate.

Environmental Effects: Birds may begin returning to roosting positions, then stop, then appear confused. Cows may orient toward the partially-dimmed sky but will not lie down. This is correct behavior for the penumbra. Totality-adjacent behaviors at 40–60% intensity are within expected parameters.

Handling: Approach PENUMBRA-7™ with calibrated expectations. The umbra is 70–250 km wide. The penumbra is up to 6,400 km wide. You are far more likely to end up here than there. This is a mathematical reality. It should have informed your planning. If it did not, that is a planning problem, not a product problem.

Storage: Cannot be stored. Passes through the Earth's surface at approximately 1,000 mph during a solar eclipse. Will not wait for you to retrieve your camera from the car. Will not circle back.

Incompatibilities: Totality. Absolutism of any kind. Anyone who claims the partial eclipse was "just as good, really." That person is wrong. The partial eclipse is not just as good. Acknowledge this and move on.

Engineering Controls: None applicable. You cannot engineer around orbital mechanics. Several companies have attempted to sell you products claiming otherwise. Those products are binoculars with branding.

Required PPE: ISO 12312-2 certified eclipse glasses; realistic expectations (see Section 4); comfortable shoes (you will be standing in a field for several hours; the field will likely be muddy; this is traditional).

Stability: Highly stable under all conditions except user hope. User hope does not destabilize the penumbra itself — the penumbra is fine, has been fine for 4.5 billion years, will be fine — but it destabilizes the experience of the penumbra significantly. This is the user's problem.

Conditions to Avoid: Expecting more than partial. Marketing materials describing the penumbra as "a preview of totality." (It is not a preview. It is its own complete shadow. It is simply not a very impressive one.) Tour operators who book "eclipse experiences" without specifying path-of-totality vs. penumbral-zone locations.

Incompatible Materials: Totality (see Section 7); antumbra (sold separately; requires Earth to be at or beyond the lunar umbral cone apex; you are probably not at that distance); complete satisfaction.

Hazardous Decomposition Products: Under no conditions does penumbra decompose into umbra. Umbra is not a decomposition product of penumbra. This is not a chemistry problem where the reaction can be pushed in the desired direction by changing temperature or pressure. It is a geometry problem. Geometry does not have a customer service line. We have verified this.

Acute Toxicity: Not toxic. The sun is present and the penumbra is not blocking enough of it to cause any unusual effects beyond what the sun normally does. Stop looking directly at it. You know not to look directly at it. Eclipse glasses. Goodbye.

Chronic Toxicity (Occupational): Extended pursuit of total solar eclipses that repeatedly results in penumbral exposure has been associated with: significant travel expenditure; emotional dysregulation on subsequent clear-sky days; marital strain; a recurring bitterness toward residents of the path of totality; an irrational conviction that next time will be different. Causal relationship to PENUMBRA-7™ has not been established. Confounders include poor map interpretation, low-cost airfare decisions, and the inability to accept that the path of totality is simply not always near you.

Reproductive Toxicity: No data. Several eclipse chasers have reported difficulty explaining their hobby to romantic partners in a compelling way. This is attributed to social dynamics and not to the penumbra or its chemical properties (which it does not have, as it is a shadow).

Environmental Fate: PENUMBRA-7™ passes over the Earth's surface and dissipates naturally at the conclusion of the solar transit. No cleanup required. No residue. The Earth returns to normal illumination within minutes. The eclipse chasers take longer to disperse and have rented most of the motels within 50 miles.

Effects on Wildlife: Birds exhibit approximately 40–60% of the behavioral responses observed under totality conditions. They begin preparing to roost, then do not fully roost, then stand around looking uncertain. Insects exhibit partial crepuscular behavior. Cows orient toward the sky but do not lie down. The 40–60% figure is reliable and should be applied to all expectations when using PENUMBRA-7™.

Bioaccumulation Potential: Cannot bioaccumulate. Is a shadow. If shadow appears to be accumulating, you are witnessing the onset of night, which is unrelated and proceeds on its own schedule regardless of what the moon is doing.

PENUMBRA-7™ requires no disposal. It self-terminates at the conclusion of the orbital event with no action required from the user.

Disposal of the experience of having been in the penumbra: varies by individual. Options include therapy, whiskey, writing a 1-star review of the eclipse on TripAdvisor, or quiet acceptance that next time you will book travel to a location within the actual path of totality even if it requires a transatlantic flight. All options are valid. The last option is recommended.

Eclipse glasses: do not dispose of in general waste. They are reusable for all future eclipses. Store in the original case or a small pouch. You will need them again. Next time, use the map.

UN Number: Not assigned. The UN Committee of Experts reviewed the question of UN numbers for astronomical shadow types in 2018 at a session in Geneva. The chair ruled it outside scope. The chair was correct. No one is transporting a shadow. The shadow moves on its own.

Transport Hazard Class: Unclassified. PENUMBRA-7™ travels at approximately 1,000 mph without a transport license, road permit, airspace clearance, or any communication with any transport authority whatsoever. The DOT, FAA, and IMO have each reviewed jurisdiction and each declined it. The shadow will be where it will be.

Special Transport Precautions: If you wish to intercept the penumbra's path, plan your travel accordingly. Allow extra time for parking, which in typical field locations will be in an unpaved area managed by a local volunteer organization that has never managed a parking area of this size before and is doing its best.

OSHA Status: PENUMBRA-7™ is not a chemical. The Hazard Communication Standard technically does not apply. This SDS was prepared voluntarily following the complaint volume received after the April 2024 total solar eclipse, during which a statistically significant number of observers were in the penumbral zone despite having access to accurate maps showing the path of totality. We felt something needed to be said formally.

EPA Status: Not a pollutant. Not a contaminant. Will not appear on a Superfund site list. Is a shadow. The EPA reviewed a preliminary inquiry in 2020 and responded that this was "not an environmental issue in the regulatory sense" and that they "appreciated the creativity" of the inquiry.

EU Regulatory Status: Under proposed EU Directive 2024/1188/EC on Astronomical Phenomenon Disclosure (in committee; not yet adopted; expected 2028 at earliest), PENUMBRA-7™ would require disclosure at point of sale as "not totality." The designated point-of-sale is outdoors. The sky is the disclosure mechanism. The sky is already disclosing it. The directive may be redundant.

California Proposition 65: The State of California has not determined that penumbral exposure causes cancer or reproductive harm. The State of California has, however, expressed concerns about many other things, including several that are also not chemicals. Users in California should consult their county eclipse guidance addendum, Form ECL-2024-P, available from county agricultural extension offices in counties that have agricultural extension offices, which is not all counties.

Legal Note Regarding Liability for the April 2024 Eclipse Complaint Volume: The entity responsible for the path of the eclipse — specifically, the Moon — has no legal mailing address, no registered agent, no domicile for service of process, and is not incorporated under the laws of any jurisdiction. Seventeen letters were sent. None were delivered. This is not a postal error. All pending litigation arising from penumbral dissatisfaction is noted and is unlikely to be resolved.

Prepared By: Shadow Quality Assurance Division, Orbital Mechanics Group, in consultation with Legal, Regulatory Affairs, and one (1) extremely tired astronomer who asked not to be named and whose request we are honoring, although it was a very specific request with multiple conditions attached, which is a lot.

Disclaimer: This Safety Data Sheet has been prepared in good faith for informational purposes. It does not imply warranty of fitness for purpose, guaranteed satisfaction, or the possibility of achieving totality from within the penumbra zone. No such warranty exists. You were in the penumbra. It is a real thing. It is a valid type of eclipse. Many people would have been glad to see it. Please sit with that before you send another contact form submission.
