## 1 Introduction A product Safety Investigation (SI-4) was carried out to determine all relevant product safety properties needed for transport and storage classification, safe handling recommendations and data points for safety data sheets of the product. The SI-4 report is part of the Process Know How Book. 

## 2 Conclusions 2.1 According to the test criteria as prescribed in the United Nations Model manual of tests and criteria (Ref. 12.1) and based on the test results, the product has to be classified as: – Organic peroxide type : D – UN number : 3105 – Packing method : OP 7 – SADT : 110°C – Emergency temperature : n.a. – Control temperature : n.a. – Minimum storage temperature : - 25°C 2.2 The product is not listed in the UN Model regulations on the transport of Dangerous Goods and relevant transport approvals have to be applied for. 2.3 The product should not be included in the German Sprengstoffgesetz. 2.4 The flash point of the product is 63 °C. The auto-ignition class of the product is T 3 (as a standard). 2.5 The burning rate of the product is 1.8 kg/min.m 2 . Based on this burning rate and according to storage directives the product will be classified for storage as: – according to PGS8 (The Netherlands) : storage group 2 – according to BGV B4 (Germany) : OP II – according to CS21 (UK) : to be discussed – according to SÄIFS (Sweden) : Group II – according to Arrêté 6 novembre 2007 (France) : group 2 2.6 The impact sensitivity of the product is low. 2.7 The sensitivity to static charging of the product is high. 2.8 The product does not show an increase in hazard due to physical changes at low temperature. 2.9 The product does not show an increase in hazard due to concentration. But in case of spill loss of solvent over a longer period of time will result in unacceptable increase of active oxygen (see discussion).A product safety investigation (SI-4) of Trigonox 501-CS40 STM 20140151

## 10 Discussion s developed as a non-crystallizing alternative for Trigonox 301. The crystallization temperature of is below - 25°C. The crystallization temperature of a wax free was around 0°C. However, evaporation of the relatively volatile solvent Spirdane D60 may be a risk. Loss of solvent over a longer period of time will result in unacceptable high active oxygen levels. Therefore, spills should be disposed of as soon possible to avoid drying out. Next to that it is recommended to use HDPE bottles for samples, because it was found that the solvent evaporates rather easy through LDPE. Based on the result of the Koenen Test with active oxygen of 7.45% (violent), the proposed classification for this product is maximum 41% (active oxygen 7.3%). Also see Test Report (Ref.12.15)
